Establish the Water Duty
Flow, pressure, water composition, temperature and inlet conditions define the water duty. Gas, particles and changes in operation also affect the choice.

Less Electricity.
The Same Volume Pumped.
At Kong 6 Well, replacing a multistage pump with an EHIK pump reduced metered electricity use by 39.5% for the same volume of gas-field water.
Recorded outcome
39.5%Less Electricity for the Same Water Volume.
In 2015, EHIK replaced the old multistage centrifugal pump at Kong 6 Well in PetroChina's Zigong Operating Area. Our project records show stable operation and fewer repairs after the change.
The energy result comes from meter readings on site during normal operation. It compares electricity use for the same volume of gas-field water—not just the two motor ratings.

A useful comparison for your site
Compare the Operating Duty,
Not Just the Nameplate.
A good replacement starts with what the system really needs and how much power the old pump uses.
Define a Fair Energy Baseline
Measure electricity use and pumped volume over a typical period. A fair comparison keeps changes in running hours or volume separate from changes in pump performance.
Coordinate the Replacement
EHIK reviews the duty and connections with you, then proposes a pump that fits your system. Custom flanges can match your existing piping.
