IDENTIFY THE RIGHT BUILD
Models & configuration
A family or hydraulic size is the starting reference. Include the complete nameplate designation, serial number, materials, seals, drive and connection details when ordering.
PFV-7272-inch tube reference explicitly listed in the temperature limitation; maximum 46 °C.
Enquire with this reference →Materials & performance
PVDF tube and impeller; Alloy 625 shaft; FKM O-ring.
Confirm the concentration and exact tube length. Apply the lower published temperature limit for PFV-72.
DFIN reviews the operating point together with the suction condition and drive. Supply the fluid properties at both start-up and normal operation so the proposed arrangement can be checked against the appropriate curve.
Application industries
DFIN application links identify duties to discuss, subject to the specified fluid and complete pump configuration.
Typical duties to review
- Compatible corrosive chemical transfer
Compatible parts & service
Use the model, tube length, serial number and motor identification to specify the impeller or rotor, shaft, seals and other service components. HVDP assemblies also require the correct stator.
Confirm whether the requested supply includes tube, motor, hose, nozzle and connections. These components are not assumed to be included with a bare pump tube.
Maintenance planning
Use the selected model’s operating manual for isolation, draining, inspection and reassembly. Report leakage, unusual noise, loss of output or visible wear with photographs and the operating history. DFIN can use the equipment identity and drawing positions to prepare a parts enquiry.

DFIN technical notes for PFV
Shanghai Dfin Pump Co., Ltd. has reorganised the available product facts into practical notes for identification, selection, application review and maintenance planning. These notes support an initial comparison; the final duty point and order code still require project-specific confirmation.
PERFORMANCE NOTE
PFV: how to read the operating range
Maximum flow — electric-drive envelope: 151 L/min; Maximum head — electric-drive envelope: 24 m; Maximum published viscosity: 2,000 cP; Published temperature range: 1.7 to 49; PFV-72 maximum 46 °C. These figures describe the documented family or model reference; the usable duty point must be checked against speed, liquid properties, suction conditions and the selected drive.
MODEL IDENTIFICATION
PFV: model and configuration checklist
Identification references include PFV, PFV-72. Use the complete nameplate designation, serial number, connection, materials, seal arrangement and drive details when requesting a replacement or quotation.
APPLICATION REVIEW
PFV: materials and suitable duties
PVDF tube and impeller; Alloy 625 shaft; FKM O-ring. Typical duties to review include Compatible corrosive chemical transfer. Confirm the concentration and exact tube length. Apply the lower published temperature limit for PFV-72.
SERVICE PLANNING
PFV: maintenance and spare-parts preparation
Use the model, tube length, serial number and motor identification to specify the impeller or rotor, shaft, seals and other service components. HVDP assemblies also require the correct stator. Isolate the equipment, follow the applicable maintenance procedure and confirm every replacement item against the installed configuration before ordering.
PRODUCT & ENGINEERING FAQ
Questions about FTI / Finish Thompson PFV
Use these answers to prepare a technically complete comparison and enquiry.
How should FTI / Finish Thompson PFV be selected?
Start with the real duty point: fluid, flow, differential pressure or head, temperature, viscosity, solids, suction condition and operating pattern. DFIN then reviews size, materials, sealing and drive.
Are the listed maximum values a guaranteed operating point?
No. They describe independent catalog boundaries for the family or model. The selected point must be checked against the applicable curve, size, speed, fluid and drive arrangement.
What information confirms the complete model code?
Provide the full nameplate designation and serial number plus materials, seal arrangement, ports, drive, motor supply and any special option. A family name alone is not an order code.
Can DFIN help identify service parts?
Yes. Send the equipment identity, drawing position, existing part code, photographs, material and failure description. DFIN can prepare a parts enquiry matched to the installed configuration.
What should be included in the quotation request?
Include quantity, fluid data, operating point, installation, connection standard, available utilities, hazardous-area requirements and delivery destination. For a replacement, include the nameplate and current drawing.
