Metering Pumps for Chemical & Petrochemical Plants
Metering and dosing pumps for chemical and petrochemical plants, built in Mumbai by Jagdish Engineering Works (JEW). We supply plunger and diaphragm metering pumps and relief valves for acid, alkali, solvent and additive dosing in batch and continuous processes.
Process chemicals are often corrosive, toxic or costly. A correctly specified metering pump doses the exact quantity every stroke and keeps the chemical contained.

Chemicals we dose in chemical and petrochemical plants
| Chemical | Where it is used | Usual pump type | Usual liquid end |
|---|---|---|---|
| Sulphuric acid | Neutralisation, reactions | Diaphragm or plunger | Alloy 20 |
| Hydrochloric acid | pH control, pickling | Diaphragm | PVDF / PTFE |
| Caustic soda | Neutralisation, scrubbers | Plunger | SS316 |
| Solvents | Process feed, blending | Plunger | SS316 |
| Catalysts and additives | Reactor feed | Plunger or diaphragm | SS316 / Hastelloy-C |
| Corrosion inhibitors | Process and utility lines | Plunger | SS316 |
| Hazardous or toxic liquids | Any service needing zero leakage | Diaphragm | PTFE-lined head |
This table is a starting guide. The right material depends on chemical concentration and temperature, so we confirm it with you before quoting.

Frequently asked questions
Which pump should I use for a toxic or hazardous chemical?
A diaphragm pump is usually preferred because the diaphragm seals the chemical in and there is no gland leakage. We will suggest a liquid end material to suit the chemical.
Can one pump dose two chemicals?
Yes, with a multi-head (duplex or multiplex) pump. Each head has its own stroke adjustment, so each chemical is set separately.
What information do you need for a quote?
The chemical and its concentration, temperature, required flow (LPH), discharge pressure, and the power supply available at site.
