Abstract: The invention relates to a pinch valve comprising at least a body having connecting flanges, a sleeve made of elastic material and an actuator, wherein said pinch valve comprises first pinching means that is movable towards the sleeve, wherein as a response to an operation of the actuator, said first pinching means squeezes the sleeve at least partially to control a flow in said sleeve. In the pinch valve, the sleeve is curved, and said connecting flanges are not parallel, whereupon said sleeve is fixed to the body in such a manner that openings of said sleeve are not parallel either.

Abstract: This invention concerns peristaltic pumps and an adjustment mechanism for adjusting a compression force imposed on a hose. The adjustment mechanism includes at least a gear unit and a counterpart for the gear unit. The counterpart is operatively coupled to a rotor, wherein the gear unit in cooperation with the counterpart are configured to adjust a gap between the rotor outer surface and the pump cavity inner perimeter.

Abstract: A peristaltic pump that includes an assembly including a rotor configured to compress a hose/tube being positioned on a pump cavity inner perimeter and an adjustment mechanism configured to adjust the compression force imposed on the hose/tube. The adjustment mechanism includes a gear unit and a counterpart for the gear unit. The counterpart is operatively coupled to the rotor, wherein the gear unit in cooperation with the counterpart is configured to adjust a gap between the rotor outer surface and the pump cavity inner perimeter. The assembly is fixed to a sliding guide that is configured to support the hose/tube.

Abstract: The invention concerns a peristaltic hose pump and an equipment for the peristaltic hose pump. The pump includes a rotor configured to compress a hose/tube being positioned on the pump cavity inner perimeter. The rotor is coupled to a one end of a crankshaft of the pump body and the pump includes a device to receive an equipment for rotating the rotor manually. The equipment for rotating the rotor includes a connection point that is configured to connect the equipment to the pump. The equipment includes also weight configured to act as a counterbalance to the rotor in order to maintain the position of the rotor.
