Pumps and Reservoirs


1 Gallon & 1 Quart Air Ram Pump System

The EP1300N series include machine variations to suit a range of can & pail sizes together with differing material characteristics, such as paste, silicone or grease. Systems are designed for quiet operation when handling medium to high viscosity fluids.

A low-pulse pump design that when used in conjunction with a fluid regulator, makes the system suitable for automatic production dispensing applications. These applications require a constant supply of air-free material.  Air bubbles and material voids, caused by handling or decanting high viscosity fluids, are prevented.

The extruder pump body is fitted with a follower-plate that seals and follows the material as the level drops to wipe the sides of the can clean limiting waste. The fluid is pressure fed by reinforced hoses to a valve, which is either mounted to a robot or operator held with a gun handle. The valve is actuated by a valve controller.

The EP1301N is designed for a 1kg (1qt) can of medium to high viscosity fluid. The EP1303N is configured for a 3kg (1 gallon) can of similar viscosity. Both systems are rated at 15:1 and provide a maximum of 996psi regulated material pressure.


  • Material delivered air-free
  • Wipe-clean action
  • Air rams to assist pumping of materials
  • Follower-plate change for 1kg (1qt) and 3kg (1gallon)
  • Adjustable air ram pressure
  • Electrical extruder motor
  • Simple load mechanism also provides easy cleaning
  • Teflon wetted parts
  • Avoids waste
  • No need to transfer material
  • Easy hook up for automatic systems
