Frequently Asked Questions

Which pumps has EHIK replaced with pitot tube pumps?

Multistage centrifugal pumps, a plunger pump and belt-driven pitot tube pumps from another supplier, in natural gas, carbon black, chemical and wastewater service.

How much energy can a replacement save?

At PetroChina’s Shunan Gas Mine the motor rating fell from 95 kW to 45 kW and electricity use dropped by 39.5% for the same volume of water pumped. Savings depend on the duty and the pump being replaced.

Can EHIK replace a Roto-Jet pump in the same way?

Yes. The same selection process is used for an installed Roto-Jet® pump: the duty, materials and installation dimensions are compared before an alternative is proposed.
