STEINLE FILTER PRESS PUMPS 2025 | 1 » All about your flow

We began our journey in 1980 in Kungälv, a small town on the Swedish west coast, as a family company with an ambition to one day become a global player on the pump market. Since the foundation, we have taken pride in delivering a wealth of knowledge and passion for pumps to the industry, whilst supplying a wide range of premium products for various industrial applications. Over the years, the company has developed into a global Tapflo Group with branches and distributors present in nearly every region of the world. One thing did not change - we are still a family company. Our solutions are designed...

The STEINLE Filter Press Pumps The STEINLE pump is a single or double acting piston diaphragm pump with a hose as the diaphragm. The liquid transferred to the filter press requires exceptionally high performance pumps. They have to supply large quantities of liquid into the empty press as well as small quantities at high pressure when the filter press is filled. This pressure must be maintained for a long period of time. The pumps are available in FP & FH series with different pressure transmission: FP - 1 : 2.4 FH - 1 : 3.3 Features & Benefits Self-regulating for filter press applications By...

Working principle Compressed air is moving the pneumatic piston which is attached to the hydraulic piston. Discharge Discharge side The hydraulic piston is moving the hydraulic liquid which is acting on the diaphragm hose which also restores its original shape. Pumped liquid Compressed air While the hose is compressed, the slurry inside is displaced and flows out. Stroke direction Hose diaphragm Ball valves on the top and bottom of the hose ensure that the flow is in one direction only. Hydraulic liquid Opened Suction side Suction The two extreme deformation conditions of the hose. The installation...

Performance curves The performance curves are based on water at 20 °C. Other circumstances might change the performance. Example FP 40 With an existing pressure of 5 bar in compressed air supply, the pump delivers 3,5 m³/h at approximately 4 bar. Air consumption will be 0,65 m³/min in this case. The amounts given apply to water at 20 °C, without suction lift. With higher viscosity liquids and a suction lift, a reduction in the flow rate may occur.
