Mud Sucker 2FAC-M, The Professionals Choice for Engine Powered Diaphragm Pumps.

Mud Sucker 2FAC-M gas powered diaphragm pumps are ideal for portable or stationary pumping applications that require a heavy duty engine for tough pumping jobs at lower volumes. Compact 2FAC-M models are self priming and light weight for easy transportation and mobility. The 2FAC-M is a positive displacement pump that can run dry without damage. The 2FAC-M is designed to pump debris laden liquid or slurries at remote outdoor locations or where electrical power is unavailable.

Advanced Technology Flappers

Wastecorp’s exclusive EPDM flapper material is designed to pump the tough stuff including general wastewater, septic waste, sewage, waste oil, food processing waste and much more.

Diaphragm Pump Protection

The Mud Sucker 2FAC-EC includes a standard pressure relief valve that stops the pump when a blockage occurs. Since a diaphragm pump is also a positive displacement pump, a pressure relief valve reduces the chances of damage in an over pressurization event.

Productivity Enhancing Accessories

Genuine Mud Sucker accessories like wheel kits, trailer mounts, lifting bails, non-collapsible hoses, pump strainers are also available for your 2FAC-M.
