Metering Pumps

How Do Metering Pumps Work?

Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn in on the reciprocal stroke of the displacement body and forced into the dosing line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering.

Microprocessor Technology Since 1988

Microprocessor technology allows the pumps to be controlled with accuracy. Sophisticated monitoring functions ensure operational reliability and guarantee minimal chemical consumption yet optimum disinfection. Interfaces integrate the pumps into a fully automated process.

Ürünler

Capacity range S2Cb: 61 – 353 l/h, 16 – 4 bar

The Sigma control type is a smart motor-driven metering pump that is setting new standards in terms of productivity, reliability and safety.

Capacity range 0.4 – 2.4 l/h at max. 1.5 bar back pressure

The peristaltic pump DULCOFLEX DF2a meters chemicals functionally, cost-effectively and quietly – ideal for use in swimming pools, hot tubs, and in spa and wellness facilities.

3 variants with maximum flow rates of 200, 410 and 660 l/h at up to 8 bar back pressure

The valveless peristaltic metering pump DULCOFLEX DFYa delivers precise, linear and reproducible metering in all process conditions. It is highly suited to outgassing, viscose, shear-sensitive media, possibly containing particles – ProMinent is therefore setting new standards in metering with peristaltic pumps.

Feed rate of 10 ml/h to 65 l/h at up to 7 bar back pressure

DULCOFLEX DFXa meters outgassing, viscous, abrasive or shear-sensitive media and is setting new standards in metering. Linear and reproducible metering (± 1 %) is guaranteed with this peristaltic pump under all process conditions. Hose replacement is a very simple process.

Capacity range of the Sigma: 25 – 1,000 l/h, 10 – 4 bar

The hygienic design version of the sigma diaphragm metering pumps is optimised in terms of dead space, features as few gaps as possible and has smooth, wetted surfaces for flexible and easy use in hygienically sensitive applications.
