Frequently Asked Hydraulic Questions

Can you cross-reference hydraulic pumps from other manufacturers?

Yes. We provide direct interchange for major brands including Parker, Eaton, Rexroth, and Danfoss. Provide the OEM part number or model code, and we will identify the compatible AIMRSE replacement with matching mounting, shaft, and port configurations.

What is load sensing and when should I use it?

Load sensing is a pump control strategy that matches pump output pressure and flow to the actual load demand, significantly reducing energy consumption and heat generation. It is ideal for variable flow applications like excavators, cranes, and agricultural equipment.

Do you provide complete hydraulic power units (HPU)?

Yes. We design and build custom HPUs including reservoir, pump/motor group, filtration, cooling, and control valves. Specify your flow, pressure, and duty cycle requirements for a complete quotation.

What is the typical lead time for a custom pump or motor?

Standard catalog pumps and motors ship within 3–5 business days. Custom-configured units with special seals, porting, or controls typically require 2–4 weeks including assembly and testing.

Do you offer explosion-proof or ATEX certified valves?

Yes. We supply solenoid valves and pressure switches with ATEX, IECEx, and CSA certifications for use in hazardous areas (Zone 1/2, Class I Div 1/2) common in oil & gas and chemical processing.

What filtration level is recommended for your pumps?

For optimal service life, we recommend maintaining fluid cleanliness at ISO 4406 18/16/13 or better for axial piston pumps. Gear pumps are more tolerant and can operate at ISO 20/18/15.
