Assembly kit rotor for Bornemann E4L 375 progressive cavity pumps / mono pumps
Contains some small parts that you need to mount a rotor.
1 Zyko sleeve
2 protective caps
Our recommendation: Change the stator together with the rotor. It usually wears out faster than the rotor and should be replaced now at the latest. – It is best to purchase both from a single source. This will ensure that the rotor and stator are properly matched.
For a complete maintenance, you should also check the joints on the rotor and on the drive shaft and replace them if necessary.
Our tip: You can send us your old joints. We will then check and renovate them for you. In most cases, this is possible with the replacement of some wearing parts. This is good for the environment and easy on your wallet!
Before reassembling, also check the large flat gasket between the pump housing and the bearing housing. Is it cracked or otherwise damaged?
