Frequently asked questions

Find answers to common questions about our products and services
  • Yes, this kit is designed specifically for 55-gallon drums. It features 2" Male NPT threads that thread directly into standard drum and tank bungs, allowing for a secure, leak-free installation without adapters.

  • Yes, this is an air-operated double diaphragm pump and requires a compressed air source. A 1/4" air filter/regulator is included in the kit to condition and regulate the incoming air supply before it reaches the pump.

  • The included suction tube is 35" long, which is sized to reach the bottom of a standard 55-gallon drum so fluid can be drawn down to the lowest level.

  • The 3/8" return port provides a dedicated connection point in the bung for a thermal relief valve, if one is needed. It gives excess fluid a path back into the drum when system pressure or temperature triggers the relief valve, helping protect the pump and plumbing.

  • No additional mounting hardware is needed. The kit ships with a mounting bracket and all necessary hardware, so the pump assembly can be mounted and put into service right away.
