Frequently Asked Questions

Q What are the key dimensions I should check before installing the RPF pump?

Before installation, you should verify the inlet/outlet port sizes, the overall length and height of the pump body, the mounting hole pattern and bolt circle diameter, as well as the shaft diameter and keyway dimensions. Referencing the pump dimension diagram above ensures the unit fits your system's space constraints and connection requirements.
Q How do I use the pump dimension drawing to select compatible fittings and piping?

The dimension drawing provides the exact port type and thread specifications (e.g., NPT, BSP, or flange standard) along with port diameters. Match these specifications to the corresponding fittings and pipe sizes in your hydraulic or fluid system to ensure leak-free, secure connections.
Q Are custom dimensions available for special application requirements?

Yes, custom configurations are available for OEM and large-volume orders. If the standard pump dimensions do not match your application's spatial or connection requirements, please contact our engineering team with your specific dimensional tolerances and flow requirements so we can provide a tailored solution.
Q What units of measurement are used in the pump dimension drawing?

All dimensions in the drawing are expressed in millimeters (mm) unless otherwise noted. If you require measurements in inches, a conversion factor of 1 inch = 25.4 mm applies. Please refer to the title block or legend on the dimension diagram for any additional notation or tolerance information.
Q How does the pump's physical size relate to its flow rate and pressure capacity?

Generally, larger pump body dimensions correspond to a higher displacement volume per revolution, which results in greater maximum flow rates. However, pressure capacity is primarily determined by the internal construction, material grades, and seal design rather than external dimensions alone. Always cross-reference the dimensional drawing with the pump's technical datasheet for performance specifications.
Q Can the pump dimension drawing be used for maintenance and replacement planning?

Absolutely. The dimension drawing is an essential reference when ordering replacement parts, seals, or bearings. It helps maintenance engineers confirm compatibility with existing mounting brackets, piping layouts, and coupling interfaces, reducing downtime during scheduled maintenance or emergency replacements.
