The Schäfer piston pumps in the Mudline series are specially designed for water suspensions such as drilling fluids with or without bentonite. With our on-and offshore sludge pumps, ease of maintenance and reliability are our top priorities. The triplex piston pump SPH series is conceived for continuous operation under full load. The pumps easily reach working pressures of up to 500 bar. The SPH series is available in three different sizes, in the power classes 700, 1200 and 1600 kW.
