Dosing Pump in Kolkata
QuaSys Inc. is an authorized dealer of Toshcon and SEKO Dosing Pumps in Kolkata, supplying precision solenoid diaphragm metering pumps for chemical dosing in water treatment, RO plants, STPs, ETPs, and cooling water systems. We serve clients in Kolkata with correct pump sizing, chemical compatibility guidance, and after-sales service.
Kolkata is India's third-largest city and East India's commercial and industrial capital. The West Bengal Pollution Control Board (WBPCB) enforces effluent discharge norms for Kolkata's tannery, jute, chemical, and engineering industries. The Hooghly River pollution control remains a priority area for WBPCB and NGT. Kolkata's large residential sector and industrial estates create significant water treatment equipment demand.
✅ QuaSys Inc. — Authorized dealer with 20+ years experience and 500+ installations across India.
We supply genuine Dosing Pump to clients in Kolkata with fast logistics and post-sales support.
What is a Dosing Pump?
A Dosing Pump (also called a Metering Pump or Chemical Feed Pump) is a precision positive displacement pump designed to inject an exact, adjustable volume of liquid chemical into a process stream at a controlled rate. QuaSys Inc. supplies Toshcon (diaphragm solenoid) and SEKO (motor-driven diaphragm) dosing pumps — industry-standard brands widely used in water and wastewater treatment across India.
Dosing pumps deliver chemicals including sodium hypochlorite (chlorine), ferric chloride, polyelectrolyte, antiscalant, pH correction acids and alkalis, coagulants, and biocides at flow rates from 0.5 LPH to 2,000 LPH with accuracy of ±1–2%.

Frequently Asked Questions — Dosing Pump in Kolkata
What is the price of a Toshcon or SEKO Dosing Pump in Kolkata?+
Toshcon solenoid dosing pumps start from ₹8,000 for a 10 LPH/7 bar model. SEKO motor-driven pumps for higher flows start from ₹25,000. Prices vary with flow rate, pressure rating, and head material. QuaSys provides quotations for Kolkata clients — call +91 11 29531287.
Which dosing pump is suitable for sodium hypochlorite dosing?+
Sodium hypochlorite (bleach) requires a pump with PVDF or PVC pump head, PTFE or Viton diaphragm, and ceramic balls or PVDF ball valves. Toshcon models with auto-de-aeration are preferred since hypochlorite degasses. QuaSys recommends the correct model for your concentration and flow rate in Kolkata.
Can dosing pumps be controlled by a 4-20mA signal from a PLC?+
Yes. Most SEKO and premium Toshcon dosing pumps accept 4-20mA or pulse signals for proportional dosing control. This allows integration with flow meters for flow-proportional chemical dosing — essential for RO antiscalant and STP chemical dosing systems. QuaSys advises on control wiring for Kolkata projects.
How often do dosing pump diaphragms need replacement?+
Dosing pump diaphragms typically last 6–18 months depending on chemical aggressiveness and pump duty cycle. PTFE diaphragms last longer than rubber. QuaSys stocks replacement diaphragm kits and ball valve sets for fast supply to Kolkata clients.
What is the difference between Toshcon and SEKO dosing pumps?+
Toshcon is a solenoid-driven diaphragm pump — compact, low-cost, suitable for flows up to 30–50 LPH. SEKO uses a motor-driven mechanism — quieter, higher accuracy, suitable for flows from 10 LPH to 2,000 LPH and for more demanding applications. QuaSys recommends the right brand and model for your specific requirement in Kolkata.
