2D-SY50/100, 2D-SY40/130 electric test pump is an electric cylinder boxer Reciprocating test pump, its main use is as follows: 
 1, the general pressure test: mainly for pressure vessels, chemical equipment, and so do water pressure, sealing, strength and burst tests, and laboratory access to high-pressure liquid. 
 2, Pg ≤ 160MPa alternating pressure gauge load test. 
 Pg ≤ 100MPa pressure gauge overload test. 
 3, Pg ≤ 100MPa hose burst test. 
 Experimental medium is water kinematic viscosity ≤ 20cst (50 ℃) [mn2 / s] oil, or similar to water, oil liquid.
