ARO PD10P-FPS-PTT vs PD10P-YPS-PTT: Port Location
ARO PD10P-FPS-PTT uses end-flanged ports, while PD10P-YPS-PTT uses center-flanged ports. Compare the full model, drawing and site connections before accepting a replacement.
ARO PD10P-FPS-PTT and PD10P-YPS-PTT differ in fluid-port location: F identifies an end-flanged arrangement, while Y identifies a center-flanged arrangement. A quote that changes F to Y therefore needs a piping-fit review, even when the remaining material codes match. This guide is for buyers checking a replacement pump or comparing two offers.
What the two model codes tell you
In ARO’s current PX10P model chart, both arrangements use 1-inch ANSI/DIN flanges. For these two codes, the center body, fluid caps and manifolds are polypropylene; the hardware is stainless steel. The PTT suffix identifies polypropylene seats, PTFE balls and PTFE/Santoprene diaphragms. It does not mean every wetted component is PTFE.
These definitions come from the manufacturer’s PX10P operator’s manual, revision AB, dated March 6, 2026, model chart on page 2. Copy any additional revision or specialty suffix from the installed nameplate. Do not silently remove it when requesting a quotation.
Compare the drawing before accepting a substitute
ARO’s PD10P/PE10P sales and engineering sheet, revision H, shows separate threaded, end-flange and center-flange layouts. Its drawing dimension A is 407.3 mm for the end-flange version and 361.2 mm for the center-flange version. These are drawing references, not a complete installation envelope. Read them against the correct view and confirm the drawing applicable to the offered revision.
For an existing skid, use a marked-up photograph and a dimensioned sketch together. Record the inlet and outlet centerlines relative to the mounting surface, pipe approach direction and space available to remove each connection. Include nearby valves, guards and cable trays. A general catalogue photograph cannot establish that a replacement will fit.
Ask the supplier to identify every proposed difference on the quotation. “Equivalent 1-inch polypropylene pump” is too broad to approve against an existing piping arrangement. For connection terminology, see our guide to identifying threads and flanges before ordering.
A practical replacement-pump enquiry checklist
Send one consistent set of information to each supplier so that prices can be compared on the same basis:
- Installed identity: a readable nameplate photo, complete model code, serial number and any recorded modifications.
- Required port layout: confirm end or center position and attach photographs showing both inlet and outlet. Mark which pipe connects to each.
- Connection details: record the mating flange standard, size, bolt pattern and gasket arrangement. Ask which connection hardware is included in the offer.
- Fit constraints: provide mounting-hole spacing, pipe centerlines, available height and width, and maintenance access. Flag any dimension that cannot change.
- Process duty: give liquid composition and concentration, operating temperature, viscosity, solids information, required flow and discharge pressure.
- Installation conditions: describe suction lift or flooded inlet, inlet pressure, hose lengths and compressed-air supply under load.
- Commercial scope: state quantity, destination and required delivery date. Request a written list of supplied accessories, exclusions, documentation and confirmed lead time.
Keep a short deviation list beside the offers: original requirement, proposed change, evidence supplied and person responsible for acceptance. Leave unresolved items open instead of treating a lower price as acceptance of a different configuration.
Check the duty as well as the physical fit
یہ official ARO 1-inch EXP non-metallic product page lists a family maximum flow of 53 US gpm and maximum operating pressure of 120 psi (8.3 bar). Those headline limits do not promise that flow at that pressure in your liquid. The engineering sheet’s curves use water at ambient temperature. Ask for a duty-point review for the actual configuration and operating conditions.
A matching PTT suffix also does not establish chemical suitability. Review all wetted components, including seals, for the process and cleaning fluids. Our wetted-material compatibility checklist helps organize that enquiry.
Frequently asked questions
Can PD10P-YPS-PTT replace PD10P-FPS-PTT directly?
Do not assume a direct fit. The port locations differ. Accept a replacement only after the offered drawing, connections and site layout have been checked, along with the complete model and duty.
Does PTT mean a fully PTFE pump?
No. In these model codes it describes the seats, balls and diaphragm option. The pump body and other components must be checked separately.
Can the existing pipes be forced into alignment?
No. ARO’s manual requires supported piping and flexible suction and discharge connections. Have qualified personnel review the installation; isolate and depressurize the equipment before work.
Request a configuration check
Send WILLEE Pump the complete model code and installation details for a replacement-pump enquiry. WILLEE is the supply contact; ARO is the referenced manufacturer. Configuration, compatibility, documentation, price and availability require confirmation for each enquiry.
