Also referred to as Metering Pumps, Dosing Pumps are typically used for chemical or pharmaceutical applications, but their versatility means they can be used in almost any industry
What is a Dosing Pump?
A Dosing Pump is a type of Positive Displacement Pump offering low flow rates, high accuracy and control for repeatable product dosing. As fluid enters the dosing pump, a predetermined volume of chemical is drawn into the pump chamber. The pump then disperses this measured quantity into another fluid, such as water, enabling controlled and precise dosing.
Dosing pumps are commonly used in chemical and pharmaceutical applications, but their versatility allows them to be utilised across a wide range of industries. There are a variety of pump ranges classified as dosing pumps, including Diaphragm Pumps, Peristaltic Pumps, and with Lobe Pumps being the most common on the market.
How Does a Dosing Pump Work?
Dosing Pumps are generally operated either manually, digitally or through analogue signal feedback from fluid accessories on the system, such as flow meters or sensors. They are also frequently controlled by a signal from a central control system like SCADA where operators can monitor and control their process systems from a central control room.
Applications for Dosing Pumps
Dosing Pumps can be used for a plethora of applications in almost every industry, below are some examples of where Tapflo’s range of Dosing Pumps can be used:

What types of Dosing Pumps do Tapflo UK supply?
Tapflo UK offers a comprehensive range of Chemical Dosing Pumps to cater to almost any dosing or metering requirement. Typical materials available for Tapflo’s range of Dosing Pumps are but are not limited to PP, PVC, PE, PTFE, PVDF, Stainless Steel AISI 316L & Hastelloy C. Take a look below at some of the most common Tapflo pumps ideal for dosing operations.
Peristaltic Pumps:  Our High-Pressure Peristaltic Pump (up to 15 bar) and Low-Pressure Peristaltic Pump (up to 4 bar) with flow rates from as low as 1 l/hr. Hose & insert materials can be catered to almost any application and even the pump casing can be supplied in numerous materials to ensure that even when the hose leaks the pump can be protected from corrosion by the pumped media. Hose leak detection can be provided upon request also.
Low Energy Air-Operated Diaphragm Pumps: Provide consistent, low pulsating flow rates with high volumetric efficiency making them ideal for batching and metering applications. Available in HDPE/PTFE, Metal and Sanitary series of products they can be catered to almost any application.
We can also supply Precision Mag Drive Gear Pumps, Mechanically Sealed Lobe Pumps and Solenoid and Motor-Driven Diaphragm or Piston Pumps with traditional electric motors or stepper motors.
Tapflo’s SLES Mixing and Dilution Unit
Tapflo UK’s SLES unit is a newer product to the range that was introduced after recognising the high cost of purchasing already-diluted SLES. Instead of customers buying the product at 27% concentration, they can save money by buying it at 70% concentration and diluting it themselves for their process line. A revolutionary system for companies that use Sodium Laurel Ether Sulfate, commonly found in shampoo, shower gel and soap products. This unit uses a Centrifugal pump to mix the SLES concentration with water and is fitted with a PLC controller for accurate flow rate and batch control.
Bespoke Dosing Pumps and Systems
In addition to dosing pumps, Tapflo supplies a wide range of pumps, dosing skids, and complete systems designed to provide drop-in solutions with minimal on-site integration and commissioning – ideal for when time is critical.
A variety of accessories such as suction lances, injection nozzles, pulsation dampeners, back pressure & relief valves, tanks, control panels & controllers, probes, flow meters and filters can also be provided on request to make sourcing your dosing equipment easier. We have the solution for any application you need dosing.
Our sales team are always happy to help with any pump queries, so don’t hesitate to get in touch.
