Chemical Injection Pumps for Refinery, Oil & Gas
Chemical injection pumps for refineries and oil and gas facilities, built in Mumbai by Jagdish Engineering Works (JEW). We supply plunger metering pumps, high-pressure pumps and relief valves for continuous injection of inhibitors and treatment chemicals.
Injection points in refineries and oil and gas plants often run at high pressure, around the clock. JEW plunger pumps are built for steady, accurate injection against that pressure.

Frequently asked questions
Can your pumps inject against high line pressure?
Yes. Plunger pumps suit high discharge pressure. Share the line pressure and we will confirm the right pump and relief valve setting.
Why fit a pressure relief valve on the discharge?
If a valve is closed or the line is blocked, pressure rises fast. The relief valve opens at its set pressure and protects the pump, piping and instruments.
Do you supply for projects outside India?
Contact us with your requirement. Our works in Goregaon, Mumbai is close to JNPT port and Mumbai airport.
