Frequently asked questions

Find answers to common questions about our products and services

  • This pump is suitable for motor oil, gear oil, and transmission fluid. It is not specified for use with other fluid types, so confirm suitability with the manufacturer before using it with anything outside those three applications.

  • This is an air-driven pump with a polypropylene air motor, so it requires a compressed air supply to operate — no electrical hookup is needed. You will need to connect it to an appropriate air line before use.

  • The wetted parts are polypropylene, the check valve seats are polypropylene, and the balls and diaphragms are nitrile. This combination of materials is well suited to petroleum-based lubricants like motor oil, gear oil, and transmission fluid, but is not confirmed compatible with other chemical types.

  • This pump has 1/2" ports, so your inlet and outlet hoses or fittings should be sized to match a 1/2" connection for a proper, leak-free fit.
