e product overview The plunger pump high pressure grease ( 200Kfg~350Kfg ) reduced to quantitative valve or workpiece rated pressure range ( 10~200Kgf ). And with the elimination of Plunger pump produced by the pulsation function. Grease pump belongs to the plunger structure, pipeline pulsation obviously; And plunger pump for high pressure oil output ( up to hundreds of kilograms of pressure ), while the number of industrial equipment or quantitative valve can not afford such a high pressure, grease relief valve can be high pressure regulating and limiting in the pressure range, thereby protecting equipment or quantitative valve, prolong its service life. [ ] Products application Used in high pressure medium input device before the pipeline Input pressure: â?¤ 40Mpa Output pressure: â?¤ 20Mpa Oil inlet and outlet: G1/4 " Material: Carbon steel 7075
