Page 15: Product Description And Accessories
KM 254 en Product Description and Accessories Product Description and Accessories General Description The KM 254 are oscillatory positive-displacement pumps with hydraulic diaphragm con- trol. The operation procedure of the dosing pump is shown in the sectional drawing. The rotational movement of the drive motor (1p) is converted via the worm gearing (2p) and eccentric (3p) into the oscillatory suction and stroke movement of the piston (6p). -

KM 254 en Product Description and Accessories diaphragm gap (the manometer indicates “0” when the pump is running and when it is stopped). If one of these diaphragms breaks, the dosing or hydraulic medium penetrates into the intermediate gap and, when the ball is removed, into the valve. The system pressure is therefore impinged on the valve and the contact manometer is activated. -
