The K class progressive cavity pump was developed according to the needs of customers with space constraints. The pump body length is shortened to merely 2/3 of standard pumps. This makes the K class pump suitable in shipbuilding, oilfield transportation, offshore platforms or factory applications with tight spaces. The pump is designed to transport mediums with a maximum solid content of 45%, including water.
Stage: 1-12 stages
Type: single-head monoblock pump, double-head nonoblock pump
Single-head pump: 6 bar, 12 bar, 18 bar, 24 bar, 36 bar, 48 bar, 60 bar, 72 bar
Double-head pump: 5 bar, 10 bar, 20 bar

Progressive cavity pumps operate with a positive displacement working principle. The pump utilizes a positive displacement through interference between the rotor in eccentric motion and the fixed rotor. The seal cavities are disconnected and the rotation of the rotor inside the stator. The seal cavities are axially moved from the inlet to the outlet, this creates a pressure differential that results in the medium flowing through the different seal chambers.
The pump rotor can be produced with varying geometric designs according to customer requirements. Surface hardening or vacuum heat treatments can be applied for metal components. When these are completed, the hardness of the metal can reach HRC 65-67.
Material: NBR, NBRH, HNBR, EPDM and FKM. The various materials are suitable for different levels of mediums and working conditions.
We can provide customers with universal joint transmission parts that start with traditional pin type and pin sleeve type universal joints and go on to hygiene class, flexible type, ball tooth type and cross pin type universal joints, to deal with various torque transmissions and axial load requirements.
Packing or mechanical seals can be chosen for the shaft of the pump. The different styles should be selected based on the working conditions of the pump. Cooling and washing systems can be included to extend the working lifetime of the pump.
SEW, NORD, ABB and other high quality driving systems can installed on your new pump.
