Metering pumps
Dosing pumping equipment
By purpose, metering pumps are specialized units that perform dosing of various media: from liquid and watery to viscous substances. The mechanism of operation of the device can be adjusted for various purposes and set the necessary parameters: pumping speeds, rotational speeds, etc. Pumping equipment is also used to work with corrosive, toxic and volatile liquid compositions, since the scope of use of pumps is practiced not only in everyday life, but also in industry.
Types of metering pumps
Water treatment market segment there are three types of metering pump to buy:
- A hose is a device with a special design so that the pumping of the working medium is carried out due to the fact that roller mechanisms act on the hoses with a certain frequency. Due to this, pressure is pumped into the pump, and the liquid begins to move. It is suitable for operation at elevated temperatures and with toxic substances. Positive: fast and inexpensive repairs, ease of operation, accessibility: the price for the metering pump is relatively low.
- Membrane – works due to the membranes at the incoming and outgoing ends, pumping of the liquid medium occurs due to the reduction of the membranes from the pressure entering the system. Due to the design features, the metering pump works more productively than similar devices. Advantages: cost-effectiveness, safety of operation.
- • Plunger – operating according to the type of piston, pressure is applied due to translational and reciprocating movements. The unit has very high speed parameters, up to a thousand liters per hour. Advantages: high efficiency, compact dimensions, resistance to mechanical influences and temperature fluctuations.
Design and principle of operation of the metering pump
The design of each of the listed types of pumping equipment has its own differences and nuances, but the general structure of all units consists of: an electric motor, a drive, a regulating mechanism, a hydraulic cylinder.
All dosing pumps have a similar principle of operation – pressure injection using the main movable units.
Areas of application of metering pumps
The main areas of application of the units are:
- Arrangement of water treatment systems
- Construction of water treatment systems
