-
Sealing material of oil hose and joint should be compatible with hydraulic oil, the same time it should avoid touch with corrosive material.
-
In the hydraulic system, all the spare parts should bear the Max pressure of hydraulic hand pump.
-
Don’t beyond the Max pressure of pump.
-
Pressure should be set on zero when power hydraulic oil, to ensure that oil box can’t beyond its capacity, avoiding oil is overflow for too full.

-
If you need large capacity works and piston return, you could choose large tonnage double acting hydraulic jack (50-2000 tons).
-
You could choose double acting hollow jack when you need to go through pc strand, steel wire or anchors (50-2000 tons).
-
If you want to install jack on the some working platforms, you need a flange type hydraulic jack (10-630 tons).
-
Single acting hydraulic jack is used for smaller tonnage and stroke works (10-100 tons).
-
Matching with special tool to go through cable or rabar, you could choose single acting hydraulic hollow jack (12-100 tons).
-
Single acting hydraulic jack with lock nut can be used for long time keep pressure work site (55-200 tons).
-
Ultra thin hydraulic jack is used for narrow work space (10-200 tons).
-
Electric oil pump is matched with kinds of hydraulic jacks, it has double acting and single acting for options.
-
Hydraulic hand pump is also used for matching with hydraulic jack, clients don’t have requirement for work efficiency.
All the tonnage, stroke, height can be customized according to client’s requirements, supply the best quality and serve. Our warranty is 2 years.
The hand hydraulic pump packaging generally uses a square wooden box, which has better pressure resistance and impact resistance.
