Rocking Piston Pumps

Selecting a piston vacuum pump

Check the required pressure and flow, supply voltage, duty cycle and connection arrangement. For a pump built into laboratory or industrial equipment, also confirm the available space and cooling conditions. The listed performance needs to suit the complete machine and how it operates.

Frequently asked questions

How do I choose the size of a piston vacuum pump?

Start with the required pressure and flow at the equipment. Include the volume being evacuated, the time available and any continuous leakage or gas load. A headline flow figure on its own does not describe performance across the full operating range.

Can a piston vacuum pump run all day?

Check the duty rating and operating limits for the exact model. Provide expected running hours, cycling frequency and ambient conditions with your enquiry. Do not assume every compact pump is rated for continuous operation.

Can I use a replacement pump with different connections?

Check the pump duty and electrical requirements alongside any connection adaptor. Check the pressure, flow, supply and controls first, and consider the effect of the connecting pipework on system performance.

What information is needed for a replacement enquiry?

Send the make and model, a nameplate photograph, supply voltage and inlet and outlet details. Describe the machine it serves and whether you need a complete pump or a service part.
