Chemical Dosing Pump Suppliers in India

Toshcon, Milton Roy and SEKO dosing and metering pumps for water treatment, STP/ETP and industrial chemical dosing.

Dosing Pumps for Water Treatment and Industry

QuaSys Inc. supplies chemical dosing pumps from three makes: Toshcon, Milton Roy and SEKO. A dosing (metering) pump injects an exact quantity of chemical, such as chlorine, antiscalant, coagulant, polymer, acid or alkali, into a process. Pick a brand below, or use the table to compare.

Toshcon vs Milton Roy vs SEKO

Brand	Pump types	Range in the models we list	Best suited to
Toshcon	Solenoid-driven electronic diaphragm	TJ-MD 8 to 100: about 6 to 90 L/h, up to 10 bar	Precise proportional dosing at low to medium flow, with controllers and sensors
Milton Roy	Hydraulically actuated diaphragm	For example mRoy XA up to 66 L/h at up to 138 bar; mRoy XW up to 7,300 L/h at up to 14 bar	Higher pressure, larger duty, corrosive and hazardous chemicals
SEKO	Electromagnetic, motor-driven, peristaltic, hydraulic	Models 600 to 803: about 2.5 to 32 L/h, up to 20 bar	A wide choice of pump types, including peristaltic for contamination-free dosing

Figures come from each brand's published information and the models we list. Exact models are confirmed for your duty.

Choosing a Dosing Pump Type

Solenoid (electromagnetic) diaphragm: glandless, accurate and proportional, for low to medium flow.
Motor-driven diaphragm: adjustable flow for general chemical dosing.
Peristaltic: the liquid contacts only the tubing, which suits contamination-sensitive or aggressive fluids.
Hydraulically actuated diaphragm: for higher pressure and demanding chemicals.

Our dosing pump selection guide and chemical compatibility chart explain how to match flow, pressure and wetted materials to your chemical.

Common Dosing Applications

Antiscalant dosing ahead of an RO membrane
Chlorine and hypochlorite dosing
Coagulant and polymer dosing in STP and ETP plants
pH correction with acid or alkali
Cooling tower and boiler chemical dosing

What We Need to Recommend a Dosing Pump

The chemical and its concentration
Required flow in litres per hour
Back-pressure at the injection point
How you want to control it: manual, 4-20 mA signal or pulse

Frequently Asked Questions — Dosing Pump

Which dosing pump brands does QuaSys supply?+

QuaSys Inc. supplies Toshcon, Milton Roy and SEKO dosing and metering pumps across India. Call +91 95408 15659 with your dosing requirement.

What is the price of a chemical dosing pump?+

QuaSys Inc. does not publish fixed prices online. A dosing pump is quoted by flow rate, pressure, wetted material and control features. Share your requirement and we will send a specification-based quote.

Which dosing pump is best for chlorine or antiscalant dosing?+

Both are usually low-flow duties, so a solenoid-driven or motor-driven diaphragm pump is common. The wetted material must suit the chemical, so check the compatibility chart and send us the concentration.

What is the difference between a solenoid and a hydraulic diaphragm dosing pump?+

A solenoid pump uses an electromagnetic drive and suits low to medium flows and pressures. A hydraulically actuated diaphragm pump drives the diaphragm through hydraulic fluid, which suits higher pressure and more demanding chemicals.

How do I size a dosing pump?+

You need the chemical and concentration, the flow in litres per hour, the back-pressure at the injection point and the control method. Our selection guide walks through each step.
