Flexbimec US4048 | 30:1 Pneumatic Piston Grease Pump for 400lb Drum

SKU US4048

Flexbimec Pneumatic Grease Pumps are built with proven engineering concepts. The brass-aluminum alloy compressed air motor is simple and intuitive to use. The pumping system is equipped with a hardened steel pumping rod to withstand the toughest uses. The seals and gaskets are suitable for most multi-purpose mineral oil based lubricant grease from NLGI 00 to 3. They can also be designed to be applied in particular viscosity conditions.

Grease is a particularly viscous fluids that has a very dense appearance at the dispensing point. The viscosity of a fluid describes its ability to resist the movement of its particles.

The compression ration describes the relationship between the surface of the piston inside the pump motor and the surface of the piston that is pumping the fluid. The higher the value, the higher the fluid outlet pressure must be. Since Greases are mixtures of mineral oils and soaps (dense and inorganic substances) and therefore have a high viscosity, it is necessary to use dispensing pumps with high compression ratios from 25:1 – or 100:1.

This pneumatic grease pump is designed for long-distance grease dispensing or forced lubrication.

Particularly suitable for transferring grease in applications and centralized systems where simultaneous high pressure and high flow output at several points are required.

With high quality materials and innovative, streamline design, this pneumatic motor offers the following features and advantages:

  • The efficiency of constant flow;
  • Low noise;
  • Limited number of plunger strokes;
  • Minimum vibration;
  • Easy maintenance and part interchangeability;
  • Condensation recovery system to avoid nebulization to the surrounding environment;
  • Wide range of complimentary accessories.
