Bladed circulation pulsers with the roundabout channel and a centrifugal rotor before the first step serve for pumping of liquids within corrosion resistance of the materials applied in their design, containing not abrasive firm particles up to 0,5 mm in size in small amounts. The pump SKD is intended for work with inflow or as normally soaking up pump, after preliminary installation of the backpressure valve on the soaking-up pipeline and certainly necessary filling by liquid of the pump and the soaking-up system.
The pumps SKD can pump over liquids with the minimum surplus of pressure over a boiling point. The small anti-cavitational stock of NPSHr and very high ability of absorption are special advantages of these pumps.
The pump SKD which is self-soaking up is required filling of the pump, without filling of the soaking-up pipeline by liquid.
