Medium Pressure Pumps

Reliable Medium-Pressure Lubrication Pumps for Grease & Oil Delivery

Kirkco medium-pressure lubrication pumps are designed to deliver consistent feed of greases, oils, and lubricants at pressures that bridge basic low-pressure supply and high-pressure metering systems. These pumps are ideal for applications that require controlled pressure and continuous flow, such as feeding metering valves, lubrication manifolds, and centralized lubrication systems in industrial environments.

Air-Operated Medium-Pressure Pump

A robust air-operated diaphragm or piston pump engineered to deliver consistent medium-pressure feed of greases or oils. Its pneumatic design offers safe operation and ease of control in production environments where electric pump drives may not be ideal.

Key Features:

  • Pneumatic operation for industrial safety and reliability
  • Smooth fluid output at controlled medium pressure
  • Handles a broad range of grease and oil viscosities
  • Self-priming and dry-run capable
  • Simple maintenance and long service life

Applications:

  • Feed to metering valves and dispenser points
  • Conveyor and production line lubrication
  • Centralized system feed for moderate distances or pressure requirements

Piston-Driven Medium-Pressure Pump

A medium-pressure pump employing a reciprocating piston design, ideal for applications that need stable flow and higher pressure than low-pressure pumps can provide. Suitable for greases and lubricant fluids where precise pressure control improves downstream metering performance.

Key Features:

  • Reciprocating piston for reliable, repeatable feed
  • Smooth medium-pressure capability for moderate lubrication networks
  • Compatible with both greases and oils
  • Built for extended duty cycles
  • Can feed multiple lubrication points from a single source

Applications:

  • Feeding metering valves in manufacturing lines
  • Workshop lubrication stations
  • Machine tool applications requiring medium-pressure feed

Follower Plate Pump (Medium-Pressure)

A medium-pressure follower plate pump designed to work directly from drums or containers. By applying even pressure across fluid surfaces, it eliminates air pockets and ensures uniform feeding of lubricant to downstream systems.

Key Features:

  • Medium-pressure feed from pails, drums, and bulk containers
  • Reduces air entrainment and material separation
  • Pneumatic or optional hydraulic actuation
  • Uniform flow into metering or dispensing equipment

Applications:

  • Drum-mounted medium-pressure supply systems
  • Feeding valve clusters or distributor blocks
  • Centralized lubrication system integration
