Daniel Speck designed the first belt-driven piston pump in 1913. Since then, more than a million pumpmeister and buffalo pumps have been built. This experience forms the basis for the well-known reliability of our pumps. SPECK piston pumps work energy-efficiently and are ideally suited for safe water supply, very often used in residential buildings and farms. Piston pumps show their strengths especially with long or unfavorably routed lines, they are very well self-priming up to 8m, can run dry for a short time, and are smooth-running due to the robust cast iron housing. To ensure the safety of the entire system, each piston pump has a built-in safety valve. On request, our piston pumps can be assembled into a complete domestic water system including a horizontal pressure tank, making installation easy and convenient. The automatic ventilation device ensures automatic operation of the water supply system.
Application
Water supply, agriculture, rainwater harvesting, farming, shipping
