Manually-Operated Single-Acting Piston Pump 3/4-16 UNF or M22x1,5 Simple and reliable design Good efficiency Cartridge design to mount in manifold The hand lever position can be rotated 360° around 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.
