Electric grease pump BFG series

follower plate

The barrel pump BF-G is adapted to take the grease of penetration class 000 up to 2 straight from a 50 litre and 200 litre barrel (DIN 6644 -2 / - 4 and DIN EN 13008). PRODUCT CHARACTERISTICS  Pneumatically driven drum pump  Discharge max. 2.64 l/min (15 : 1)  Lubricant grease  Surface signal grey RAL 7004 The pump basically comprises an air motor (= compressed air cylinder) with control system and a pump section, together with a centering lid and a follower piston. The plunger-type pump is so designed as to suck lubricant during the downward stroke of the plunger and to force it to the user during the upward stroke. The grease pressure which can be achieved is approximately proportional to the compressed air pressure used for operation, multiplied by the internal ration factor of the pump. The characteristics show how the output rating depends on the counterpressure. The edge of the next plate is fitted with a rubber lip for sealing purposes. A new kind of packing between the compressed air motor and the grease pump creates a seal by hydraulic means and results in almost maintenance-free drum emptying. In the model with adjustable level control, an optical and acoustical warning signal indicates that the quantity of grease left in the barrel is down to almost zero.
