Functional Description
RC 3/4-16-UNF

RC M22x1,5

A manually-operated single-acting piston pump with two
non-return valves. As the piston (1) moves up, the
negative pressure is formed and it closes the discharge
valve (2), the pump inlet valve (3) opens and the fluid is
drawn-in through the radial opening under the pump
piston. Once the top dead centre is achieved, the piston
moves down and increasing fluid pressure closes the
inlet valve and opens the discharge valve. The fluid is
under the pressure in proportion to the action of force on
the lever and thus pushed out in the axial direction

A manually-operated single-acting piston pump with two
non-return valves. The function of the non-return
discharge valve is substituted by a special rubber cup
(2). As the piston (1) moves up, the negative pressure is
formed and it opens the inlet valve (3), while the clinging
special cup closes the radial discharge opening; the
fluid is drawn-in through the axial opening under the
pump piston. Once the top dead centre is achieved, the
piston moves down. The increasing fluid pressure
closes the inlet valve and raises the special sealing cup.
The fluid is under the pressure in proportion to the action
of force on the lever and thus pushed out in the axial

The control lever with a 500 mm (19.68 in) long handle and set of spare gaskets can be ordered as accessories.
