Roto-Sieve - Model KP -Piston Press

The KP Piston Press is a great economical option for dewatering screenings where either space is a constraint or there is a need to lift the screenings vertically at the outlet. The Piston Press combines the good dewatering capacity of a screw press with the capability of a hydraulic press to lift and transport the dewatered material. This is made possible by the flexibility of the unique drive system which utilizes a worm gear motor and a trapezoidal threaded shaft. The piston compresses the screenings in a press zone with small openings for high dewatering. To create the resistance required for dewatering, the piston press is connected to a press pipe or an adjustable counter-pressure device. Pressate and flush water is collected in a trough underneath the press housing and discharged through an outlet. Dewatered screenings are discharged via a press pipe to a bin/dumpster or continuous bagging device.
