TRANSFER · BLENDING · BATCH HANDLING

Chemical processing

Move process chemicals from storage to the next production step.

From unloading drums to feeding a blending vessel, chemical transfer brings together fluid compatibility, containment and changing batch conditions. A useful starting point is the complete liquid composition, including concentration and any cleaning fluid that will pass through the same pump.

Typical media

  • Acids & alkalis
  • Solvents
  • Detergents
  • Process additives

Process duties

  • Drum and intermediate bulk container (IBC) unloading
  • Tank-to-tank transfer and batch charging
  • Transfer to treatment or filtration equipment

What to check

Check every wetted component—not only the pump body. Diaphragms, balls, seats and seals must suit the chemical at its actual concentration and temperature. Confirm inlet conditions, required discharge pressure and the site’s hazardous-area requirements before choosing a configuration.

Send the chemical name, concentration, temperature and required flow.

PIGMENTS · RESINS · COLOR CHANGEOVERS

Paints, inks & coatings

Keep material moving through mixing, circulation and filling.

Pigment loading, viscosity and frequent color changes can make a coating-transfer duty very different from clean-water service. Define whether the pump will simply transfer a batch, circulate material or supply another piece of process equipment; each duty places different demands on the system.

Typical media

  • Water-based coatings
  • Printing inks
  • Resin blends
  • Pigment dispersions

Process duties

  • Feed mixing and holding vessels
  • Transfer finished batches to filling stations
  • Circulate process material where required

What to check

Review abrasion from pigments, solvent compatibility and the viscosity at operating temperature. Where pulsation affects the downstream process, assess the complete delivery system, including a suitable dampener. Specify the flushing solvent and changeover procedure to help evaluate cleanability and trapped volume.

Share the coating type, viscosity, solids content and cleaning method.

03 / APPLICATIONWater treatment
SLUDGE · EFFLUENT · TREATMENT CHEMICALS

Water & wastewater

Match the pump to the solids, the suction conditions and the treatment stage.

A treatment plant can involve thin process water, settling sludge and concentrated treatment chemicals within the same site. Describe each duty separately: a configuration suitable for a chemical feed line may not have the solids passage or wear characteristics needed for sludge transfer.

Typical media

  • Industrial effluent
  • Pumpable sludge
  • Wash water
  • Treatment chemicals

Process duties

  • Transfer between collection and treatment stages
  • Empty sumps and process holding tanks
  • Feed filtration equipment within its pressure requirements

What to check

Record the largest particles, approximate solids concentration and any abrasive grit or fibrous material. Check suction lift, hose length and the discharge-pressure range. For chemical dosing, define the required accuracy and control method rather than treating a transfer-pump flow rating as dosing performance.

Send a fluid description, solids details and a sketch of the suction and discharge lines.

INGREDIENTS · BATCHING · CLEANING

Food & beverage

Choose around the ingredient—and the way your line is cleaned.

Ingredient transfer can range from a free-flowing beverage to a thick sauce with suspended particles. Product texture, cleaning procedures and the required hygienic documentation all influence the choice of pump construction. Define direct food-contact service separately from utility or cleaning-fluid transfer.

Typical media

  • Syrups & concentrates
  • Sauces & liquid ingredients
  • Beverages
  • Cleaning solutions

Process duties

  • Unload bulk liquid ingredients
  • Charge mixing and preparation vessels
  • Transfer prepared product toward filling equipment

What to check

Confirm the exact food-contact materials, surface-finish requirements, connection standard and cleaning procedure. Check particle size and sensitivity to handling, together with viscosity at transfer temperature. Hygienic suitability and certificates belong to the specific pump configuration; they should not be assumed from a stainless-steel body alone.

Tell us the ingredient, temperature, cleaning cycle and documentation your process requires.

FORMULATIONS · CLEANABILITY · CHANGEOVERS

Personal care & pharmaceutical processing

Bring transfer performance and contamination control into the same conversation.

Lot changes, sensitive formulations and cleaning validation create requirements that go beyond the nominal pipe size. Describe the production stage and whether the duty involves an intermediate, a finished formulation or a cleaning liquid. This helps distinguish routine transfer from a process needing specially documented hygienic equipment.

Typical media

  • Lotions & shampoos
  • Liquid formulations
  • Process intermediates
  • Cleaning fluids

Process duties

  • Move ingredients into preparation vessels
  • Transfer formulated batches to holding tanks
  • Support defined changeover and cleaning routines

What to check

Review viscosity, allowable product handling and the full contact-material list. Specify drainability, disassembly access and cleaning-temperature requirements. If the process requires sanitary, aseptic or other validated performance, identify the relevant acceptance criteria and obtain configuration-specific documentation before making a selection.

Share the formulation properties, process stage and cleaning or validation requirements.

MACHINE SUPPORT · DRUM TRANSFER · UTILITIES

General manufacturing

Fit the transfer point into the way your production line works.

A compact pump may need to empty a drum, feed a machine or handle a maintenance transfer in a crowded production area. The installation matters as much as the fluid: access, available compressed air, hose routing and the frequency of start-stop operation can change the practical choice.

Typical media

  • Oils & lubricants
  • Detergents
  • Process water
  • Compatible solvents

Process duties

  • Supply machine reservoirs and process stations
  • Empty drums and maintenance collection containers
  • Transfer wash or utility fluids between work areas

What to check

Confirm viscosity, fluid compatibility and the pressure required at the destination. Measure suction conditions and installation space, and identify any flow-control or pulsation requirements. For intermittent duties, describe the operating cycle so that the pump and its air supply can be assessed together.

Send the fluid, transfer distance, operating cycle and available air pressure.

Explore six further applications where solids, wear, viscosity or material purity help shape the selection.

07DEWATERING · SLURRY TRANSFER

Mining & construction

Start with the solids and the conditions at the suction point.

Site water and pumpable slurries can vary as sediment settles or the work area changes. A useful duty description includes the largest particles, abrasiveness and how far the pump sits above the liquid. Thick, poorly flowing material needs a separate handling assessment.

Typical media

  • Site water
  • Pumpable slurries
  • Process chemicals

Process duties

  • Drain collection points and work areas
  • Move slurry or process liquids between stages

What to check

Check solids passage and valve design against the actual particles. Review hose diameter, suction lift and available compressed-air volume as well as pressure. Account for access to wearing components and the installation’s environmental conditions.

Share solids size, concentration, suction lift and the available air supply.

08BULK TRANSFER · SITE UTILITIES

Oil & gas

Define the service and the site requirements before choosing a pump.

Liquid handling around tanks and service areas can involve oils, oily water and treatment chemicals. Bulk transfer, lubrication and chemical injection are different duties. Establish the required discharge pressure and control accuracy early, especially where an injection application may call for another pump technology.

Typical media

  • Oils
  • Oily water
  • Treatment chemicals

Process duties

  • Transfer compatible fluids around tanks and service areas
  • Handle defined maintenance and collection duties

What to check

Confirm the complete fluid composition, temperature and material compatibility. Specify hazardous-area classification, grounding and bonding requirements and the exact certificates needed for the installation. Assess the selected configuration rather than relying on a general description of pneumatic operation.

Send the duty, fluid properties, pressure requirement and site classification.

Discuss this application
09SLIPS · GLAZES · ABRASIVE DUTIES

Ceramics & mineral slurries

Plan for wear when solids are part of the process.

Ceramic slips, glazes and mineral suspensions can place sustained wear demands on wetted components. Settling and changes in solids concentration can also alter how material reaches the pump. Define the slurry at its working condition, including what happens after a production pause.

Typical media

  • Ceramic slips
  • Glazes
  • Mineral suspensions

Process duties

  • Transfer prepared slurries between vessels
  • Feed process equipment within the required flow range

What to check

Review particle size, concentration, abrasion and viscosity together. Match valve construction and wetted materials to the actual slurry, then examine suction-line geometry and flushing arrangements. Include access for inspecting diaphragms, balls and seats in the installation plan.

Provide solids loading, largest particle size and the slurry’s operating viscosity.

10STARCH · INKS · PROCESS LIQUIDS

Pulp, paper & packaging

Support the liquid-handling steps around paper and converting lines.

Paper and packaging operations involve a wide range of supporting liquids: starch-based adhesive, printing ink, coating fluids and wash water. These services should be identified separately from bulk pulp transport, where fiber content and consistency may require a different type of pumping system.

Typical media

  • Starch & dextrin adhesives
  • Printing inks
  • Coating fluids

Process duties

  • Supply coating, printing and gluing stations
  • Transfer process or cleaning liquids between vessels

What to check

Describe solids or fiber content, viscosity and the tendency to dry or deposit inside the system. Check temperature, flushing compatibility and the downstream equipment’s delivery requirements. Define any recirculation or intermittent-use conditions that may affect material consistency.

Tell us the production step, fluid consistency and how the line is cleaned.

Discuss this application
11BATCH TRANSFER · MATERIAL HANDLING

Adhesives & sealants

Let viscosity and curing behavior guide the technology choice.

A pumpable liquid adhesive and a heavy sealant present very different transfer problems. Describe whether the material flows freely into the inlet, needs a follower plate or requires controlled dispensing. Some high-viscosity extrusion and dispensing duties call for a piston or ram system rather than a diaphragm transfer pump.

Typical media

  • Pumpable adhesives
  • Resin mixtures
  • Process cleaning fluids

Process duties

  • Transfer suitable liquid adhesive batches
  • Supply a downstream process or preparation vessel

What to check

Provide viscosity at working temperature, curing mechanism, pot life and any moisture sensitivity. Review inlet loading, shear requirements and the allowable residence time. Confirm cleaning compatibility and delivery pressure before narrowing the equipment options.

Send the viscosity, curing behavior, container type and transfer or dispensing requirement.

Discuss this application
12PROCESS SLURRIES · PURITY REQUIREMENTS

Battery materials & manufacturing

Treat material purity as a configuration requirement.

Battery-material processing may combine abrasive solids, chemically demanding liquids and strict contamination limits. Different production stages need separate duty definitions; a generic industrial pump description does not establish suitability for an electrode slurry or a controlled-purity process.

Typical media

  • Specified process slurries
  • Compatible process liquids
  • Cleaning media

Process duties

  • Transfer process liquids between preparation stages
  • Handle defined slurry duties after a compatibility review

What to check

State restricted metals and the required cleanliness level, along with solvent chemistry, particle distribution and slurry viscosity. Check every wetted component and its documentation. Where shear, air inclusion or a hazardous atmosphere matters, include those limits in the selection review.

Share the process stage, restricted materials and the slurry or liquid specification.

BEFORE YOU SELECT

A few practical questions.

Can I select a pump by industry alone?

An industry is a starting point. Confirm the fluid, operating temperature, required flow and pressure, solids and installation conditions against the exact product configuration. The pumps in the catalog are not automatically approved for every application shown here.

Does a matching body material establish compatibility?

No. Review all wetted components, including diaphragms, valve balls, seats and seals, with the fluid composition and operating temperature. Cleaning fluids and changes between production batches also belong in that review.

What if I only have an existing pump code?

Send the complete nameplate code and a clear photograph through your preferred contact method. Add the fluid and operating conditions so we can discuss the existing configuration, replacement components or a different transfer requirement.

Industry images illustrate process environments. Application descriptions guide the selection discussion; final suitability depends on the exact pump configuration and operating conditions.
