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.
Materials & performance
Select wetted materials and sealing from the manufacturer configuration.
Describe lubricity as well as viscosity. Confirm the chosen construction before using higher-viscosity or higher-temperature options.
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
- Low-viscosity filling and dosing
- Compatible chemical and personal-care liquids
Compatible parts & service
Identify gears, shafts, bushes and seals for gear pumps, or the liquid-end valves, piston seals and diaphragms for metering pumps, using the matching section drawing.
Provide the serial number, complete construction code and fluid details before a repair set is specified. Optional gear treatments, heating or magnetic drives change the required parts.
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 WP
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
WP: how to read the operating range
Published flow range: 2–16 L/min; Maximum pressure: 15 bar; Standard viscosity range: 1–60 cP; Water / low-viscosity temperature limit: 40 °C; special duties require separate confirmation. 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
WP: model and configuration checklist
Identification references include WP. Use the complete nameplate designation, serial number, connection, materials, seal arrangement and drive details when requesting a replacement or quotation.
APPLICATION REVIEW
WP: materials and suitable duties
Select wetted materials and sealing from the manufacturer configuration. Typical duties to review include Low-viscosity filling and dosing, Compatible chemical and personal-care liquids. Describe lubricity as well as viscosity. Confirm the chosen construction before using higher-viscosity or higher-temperature options.
SERVICE PLANNING
WP: maintenance and spare-parts preparation
Identify gears, shafts, bushes and seals for gear pumps, or the liquid-end valves, piston seals and diaphragms for metering pumps, using the matching section drawing. Isolate the equipment, follow the applicable maintenance procedure and confirm every replacement item against the installed configuration before ordering.
PRODUCT & ENGINEERING FAQ
Questions about CUCCHI WP
Use these answers to prepare a technically complete comparison and enquiry.
How should CUCCHI WP 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.
