The HSP series is used for pasty and highly viscous media with a low foreign body content and small particle sizes (up to 8 mm).

The precise valve sealing makes it possible to achieve very high delivery pressures. The design principle of the hydraulic and delivery pistons corresponds to that of the Putzmeister series KOS and KOV. This ensures a high level of reliability and availability.
