Air and vacuum pump drives
Describe the pump mechanism, running load, starts and duty. Confirm the selected motor winding and shaft interface against the actual pump rather than using no-load speed as a system rating.

DC Motors & Pumps for Fluid-Handling Equipment OEMs
Separate the driven mechanism from the performance of the complete fluid system. Review pump-drive motors, geared valve mechanisms and the GB-2228 diaphragm-pump assembly against the actual operating conditions.
Start with the Load, Flow and Operating Duty
A motor inquiry and a complete-pump inquiry need different information. Motor selection begins with the mechanical load, while pump selection also needs the fluid and matching pressure/flow conditions. Valve actuation introduces travel and stopping requirements. These distinctions help an equipment OEM compare the relevant platforms without treating unrelated figures as one system rating.
Equipment and Drive Requirements
Water and diaphragm-pump equipment
The related range includes motor references for diaphragm pumps and the complete GB-2228 assembly. Specify the fluid, supply, flow and pressure conditions together with connection and installation requirements.
Valve actuation
Some geared-motor source pages name valve-control uses. Provide required movement, load, end positions, duty and control method; the gearbox or motor alone does not establish valve performance or sealing capability.
Spray and fluid-transfer systems
GB-2228 source material names spraying, fluid-transfer and water-supply systems. Review the full operating point, media compatibility and fittings for the selected pump configuration before equipment evaluation.
What to Define Before Selecting a Motor
Motor, drive or complete pump
Identify what you need supplied: a motor, a geared actuator platform or a complete pump. Their relevant specifications differ, and a motor torque or power figure cannot be presented as a complete-system output.
Matching pressure and flow
For a pump inquiry, state flow at the required pressure and the intended duty. Maximum-flow and maximum-pressure references are separate conditions unless the matching operating-point data says otherwise.
Fluid and connection
Describe the fluid, temperature, inlet conditions, fittings and installation orientation. Confirm compatibility for the selected assembly; a generic pump application reference does not establish approval for every medium.
Load, travel and evaluation
For a motor or valve-drive inquiry, provide mechanical load, travel, starts and control requirements. Evaluate the proposed configuration in the complete equipment and retain its drawing and sample revision for approval.

Questions from OEM Equipment Buyers
Do you list complete pumps as well as pump-drive motors?
The current catalogue contains DC motor platforms with pump applications and a GB-2228 diaphragm-pump assembly. State which supply scope you need so the relevant motor or pump information can be reviewed.
Can the maximum flow and maximum pressure be combined?
Do not assume they occur together. Provide the required flow at the working pressure and request matching operating-point information for the selected pump and conditions.
Can a pump be used with any liquid or chemical?
Do not infer media compatibility from an application label. Send the fluid, concentration where relevant, temperature, duty and connection requirements so the selected pump materials and operating conditions can be checked.
Bring us the motor requirement for your next product.
Send your preferred model or the working point, installation drawing and expected quantity.
- Supply voltage, loaded speed and torque
- Shaft, mounting and installation requirements
- Sample quantity and expected project demand
A drawing, reference motor or application brief is a useful starting point.
