Liquid end

In order to meet the different requirements of the process applications connected with various operating conditions and fluid characteristics, the hydraulic end is defined by combining different configurations of the manifold, valve assembly and sealing systems and by selecting the most suitable materials for each specific application.

Each solution has been widely studied and field proven to meet the requirements of high reliability, easy maintenance and long life of each component.

The design of the liquid end assures very high stiffness and fatigue stress resistance of the structure offering the possibility to install pre-assembled units of valves/valve seats and cylinders/plungers/packings with consequent minimum downtime.

The arrangement of the hydraulic head shown at the top of the page is the most widely used and it is suitable for a wide range of operating conditions, hazardous fluids and/or containing suspended solids.

Other hydraulic solutions are available for high viscosity fluids and pumping conditions at high or low temperature.

Specific liquid end designs are also available for handling high pressure/high temperature fluids and medium/high pressure slurries with a significant content of solid particles (in terms of size and weight percentage).
