Stator for Bornemann E4H 236 mono pumps / progressing cavity pumps

Our stators are made in Germany and are available in various materials (elastomers) and colours. The standard stator for Bornemann E4H 236 is black inside, made of NBR material and does not have a hole for a sensor (‘TSE hole’).

Drawing position: 22

Please select the version you require. If you need a special version or are not sure: Please write a short note in the enquiry basket. Of course you can also contact our spare parts hotline and we will help you directly.

Our recommendation: After dismantling the pump, check the condition of the rotor. Is there any scoring or chipping of the chrome layer? Are there any other signs of wear? Depending on the medium you are pumping (e.g. toothpaste or media with a lot of solids), a rotor can wear out more quickly. It is best to buy the stator and rotor from a single source. This will ensure that they are perfectly matched. For a complete service, the joints and drive shaft should also be checked and replaced if necessary. Before reassembly, also check the large gasket (drawing position 25) between the pump casing and the bearing casing: Is it cracked or otherwise damaged?

Our tip: Does your stator wear relatively quickly? This may be due to the fluid you are pumping. The inner material of the stator (‘elastomer’) is suitable for different media to varying degrees. – Talk to us. We will work with you to find the ideal elastomer for your application!

Options

The elastomer is available in black colour (this is the standard) or in light colour. The light colour is used to pump light-coloured lacquers or light-coloured food. This prevents the slightest abrasion of the elastomer compound from changing the colour of the medium. Regardless of the elastomer colour, all our stators are food grade.

TSE hole: This is a pre-drilled hole for screwing in a temperature sensor. The temperature sensor can be used to stop the pump before it gets too hot. This happens, for example, when it runs dry. We can supply the stator with a suitable temperature sensor.

Inlet cone: Our stators are available with a conical inlet cone. This achieves better suction behaviour. Our recommendation: The surcharge is low and the pump sucks better. In some applications, the power consumption of your pump will even be reduced!
