Manual guided-vane pump of RSH 25-5 type is intended for pumping neutral self-lubricating liquids from standard tanks and other small barrels.
Kinematic viscosity of liquids is from 0,02*10-4 up to 0,75*10-4 m²/s (from 1,1 up to 10°E), with temperature up to 70°С.
The liquids to be pumped: engine oils, varnish, emulsion and so on.
Pump is manufactured in climatic version U1 as per GOST 15150 and is intended for both-way operation: in the enclosed spaces and out-of-doors at a temperature of ambient air from plus 40 up to minus 40°С.
Pump consists of the casing, off-centered rotor with two movable plates (gates), the front and rear covers, lever, sealing rings and the cuff.
The covers are bolted. The rotor plates are pressed to the casing by the spring fitted on the rod. To withdraw and discharge liquids the pump is completed with pipe and special pipe neck, fixed by lock nuts. To attach the pump to the barrel mouth there is a nut with fixing device.
In clockwise rotation of the rotor the plates being sliding along the casing extrude the liquid from the cavity into the pipe neck. At the same time the liquid is sucked through the pipe.
In counterclockwise rotation of the rotor the liquid is moved in the opposite direction.
