Pumps for PCB Manufacturing Equipment are designed for pumping a variety of corrosive liquids.

This group includes pumps of various designs that pump liquids that differ in their chemical properties from ordinary water. Basically, these are chemically active liquids, and according to the degree of their aggressiveness, as well as depending on other properties of the pumped liquid (density, temperature, abrasiveness, etc.), the material of the flow path and the design of the pump are determined.

By the nature of the prevailing forces in the pump, they are distinguished:

Positive displacement pumps . They are used for pumping viscous liquids under high pressure. They are sensitive to contamination of the pumped liquid and are characterized by uneven delivery. positive displacement pumps include impeller, vane, screw, peristaltic, diaphragm, piston and many others .

Piston pump. Suction and displacement of fluid in it occurs during the reciprocating movement of the piston in the cylinder. Reciprocating pumps can generate very high pressures with a small footprint.

Dynamic Unlike positive displacement pumps, dynamic pumps convert energy in stages, they can pump contaminated liquids, and have a uniform flow. They work practically without vibrations, most of them do not have the possibility of dry suction. Dynamic pumps are subdivided into vane, jet and ram .

Vane converts energy due to the dynamic interaction of the flow of the pumped liquid and the blades of the rotating impeller, which is the working body of the pump. vane pumps include centrifugal, vortex and axial flow.

The main working body of centrifugal pumps is a wheel freely rotating inside the casing, mounted on a shaft. Due to the rotation of the wheel, a centrifugal force develops, under the action of which the liquid moves.

The impeller of a vortex pump is a flat disc with short radial rectilinear blades. They have the following advantages: the pressure generated by them is 3-7 times more important, the design is simpler and cheaper, capable of self-priming, and can operate on a mixture of liquid and gas. Among the disadvantages: unsuitable for supplying a liquid containing abrasive particles, the efficiency of vortex pumps usually does not exceed 30%, their use is justified when the speed coefficient is less than 40.

The impeller of a axial flow pump consists of a sleeve on which several blades are fixed. The pumped liquid moves through the impeller parallel to the shaft axis. They are characterized by a high rate of speed, high flow, but low head.

For liquid dosing, dosing pumps are used. They provide the ability to deliver a given volume of liquid for a certain period of time with maximum accuracy, thanks to adjustable performance. Dispensers are used in laboratories and industrial plants in a wide variety of industries.

Ddrum pumps are used to pump liquids from containers, barrels, vats and other containers. They are used for pumping neutral and corrosive liquids.

Multistage pumps are one of the most versatile types of high-pressure.
