Gear pumps of the KF series are used to transport all types of liquids. The main feature of the gear pump KF is the wide range of models, which can be combined in any combination according to the modular design principle and can also be extended in the future. The pumps are also suitable for less lubricating media. The casing components of the standard sizes are made of grey cast iron. The gearbox is made of high-strength carburised steel, hardened and fixed to a shaft tile made of various materials. The drive shafts in standard sizes are sealed with radial shaft seals. All structural dimensions are in helical gear specification.

【Material Analysis】

1、Driving shaft sealing parts

2、Radial shaft sealing ring

3、Double radial shaft sealing ring (hardened)

4、Slip ring seal

5、Pressure valves for front bearing pumps and systems used to absorb radial forces on the drive side

6、Using the combination of valves in the available flange connection (universal valve), the conveying flow direction remains unchanged 

when switching the direction of rotation.

7、For the direction of rotation, the following provisions apply: when observing the shaft end of the pump, when the shaft is facing the right 

when observing the shaft end, when the shaft is rotating towards the left when the conveying direction is from the left to when the conveying 

direction is from the right to the left.
