BEKA P26-Series

The BEKA P26-series contains a range of pneumatic piston pumps used for oil and air lubrication. Oil and air lubrication is the perfect solution to lubricate bearings, especially high speed bearings. Additional fields of application include chains, gear trains and other industrial applications.

The P26-series pumps function as a multi-line pump where the lubricant gets directly transported to the lubrication points via an air-flow. The lubrication point is continuously supplied with a flow of lubricant and air.

The P26-series give you the possibility to create an simple and economical system for oil-air lubrication up to 6 lubrication points. Systems are available in various configurations and with different oil reservoir sizes, and will be configured individually for each application.
Working principle

The sprayed air is actuated via a 2/2-way solenoid valve, regulated by a pressure control valve. The pump is actuated via a 3/2-way solenoid valve. The delivery piston is pressurized via a pneumatic connection. During this process the delivery piston carries out a pressure stroke. Lubricant is supplied to the integrated metering valves which meter the lubricant and deliver it to the lubricant chamber. From there it is supplied to the lubrication points via a compressed air flow. Non-used lubricant is returned to the reservoir.

The pump is put under pressure with compressed air for approx. 4-5 seconds. When the pressure in the pump is relieved, the pneumatic piston is pressed back to its initial position and ready for a new revolution.

System overview

Reservoir
Pumps in the P26-Series are available in plastic or steel and available in different reservoir sizes.

Minimum level monitoring
Automatic minimum level monitoring is available for better reliability and a safe refill cycle.

Pressure limiting valve
The regulation of the pressure happens via a pressure limiting valve. The valve for the P26-series is adjusted to 40 bar (580 psi)

Metering valves
Lubricant is supplied to integrated metering valves. They meter lubricant and deliver it to the lubricant chamber, after which it is supplied to the lube points via sprayed air.

Lubricant outlet connection
Lubricant outlets are available as a straight outlet or with an 90º angle.

The combination of oil and air lubrication causes a sealing air flow which protects the lubrication point from outside
contamination like dust or dirt.
