How to Select the Right SEKO Dosing Pump

Selecting a SEKO dosing pump means balancing flow rate, operating pressure, chemical compatibility, and control signals — and getting any one of these wrong means process downtime, failed audits, or damaged equipment. Most buyers only discover the mistake after installation.

Trusted SEKO Dosing Pump Specialists Since 1992

Since 1992, the GM Pumps team has worked alongside South African water treatment engineers, helping them specify the right pump the first time. We don’t just supply SEKO metering pumps — we understand the applications they go into. Cooling towers, effluent treatment, reverse osmosis, steam generation, chlorination — we have specified and supported SEKO dosing systems in all of them, across every major industry in Southern Africa.

When you contact us, you speak to someone who can tell you immediately whether you need a TPG or a TPR, an AKS or an APG, PVDF or stainless wetted parts — and exactly why.

Your Long-Term SEKO Dosing System Partner

The engineers and procurement managers who have bought from GM Pumps since the 1990s keep coming back — not because we are the cheapest option, but because when something needs attention at 7am on a Monday, we answer. When a seal material needs to be verified against a new chemical, we know the answer. When a TPG needs to be reconfigured for a new flow meter signal, we walk you through it.

That is what 32 years in this industry looks like in practice.

 While predominantly serving the industrial pump markets of the coastal belt regions of South Africa with air-operated double diaphragm and positive displacement pump ranges, GM Pumps CC also has extensive experience with chemical dosing systems.

Our own “in-house” designed, South African-manufactured range of industrial chemical mixers was originally developed for use on 1000-liter IBC tanks.

These fluid mixers have proven to be an excellent addition to the existing Seko mixers and chemical-dosing product range. Available in pneumatic and electric motor variations, these units can be custom-built to the customer’s specifications.

Industrial water systems often call for pumps, flow meters, and chemical metering equipment. This equipment is needed to deliver cooling tower chemicals at precise dosages, as the plant’s flow-rate demand varies.

Seko not only designs and manufactures a high-quality range of chemical dosing pumps but also offers controllers that enable the units to deliver accurate dosages of acid or alkaline chemicals. These controllers typically operate off the generated signals (both analog and digital)  from flow meters, pH, or Redox probes. Our pH controllers enable the pumps to meter accurate chemical dosages to adjust both alkaline and acid feed into raw water or effluent streams.

Seko solenoid-activated diaphragm and peristaltic pumps are positive-displacement fluid-delivery systems in the Seko dosing pumps product line. Proven worldwide to be highly effective across industrial pump applications, including reverse osmosis and desalination, for CIP (clean-in-place) and anti-fouling programs.

GM Pumps cc has manufacturing facilities based in Bothas Hill, KZN, South Africa, and is equipped to design and supply the correct metering pump or complete chemical dosing or metering system for your application. With support from Seko S.p.a., we can provide all the assistance you need to meet your dosing pump or metering requirements.
