The THAP E air-driven oil injectors are used for mounting and dismounting OK couplings, for dismounting large pressure joints such as bearings, flywheels, couplings, railway wheels, and in many similar applications. The pumps consist of a high-pressure hydraulic pump, driven by an air piston. The units are supplied in a sturdy case including oil suction and return hoses with quick connect couplings.
The air-driven pumps can also be supplied in complete sets which consist of pump, pressure gauge, high-pressure pipe and connection nipples. They are particularly suitable for mounting and dismounting large pressure joints. This includes applications such as SKF OK Couplings, flywheels, gear wheels, railway wheels, and impellers. Compared to hand-operated oil injectors, the use of air-driven oil injectors can save considerable time and effort.
The THAP 300E is designed to have an oil outlet pressure of 300 MPa (43 500 psi). Depending on the maximum oil pressure required, they are suitable for applications such as bolt tensioning and pressurizing large hydraulic nuts. Compared to hand-operated oil pumps, the use of air-driven oil pumps can save considerable time and effort.
The THAP ...E series contains an oil pump or injector driven by an air motor, with the air pressure internally limited to 7 bar, which is used to produce high oil pressure.
The THAP ...E series are delivered ready for use. They are supplied in a transport box and include suction and return hoses with quick-connection couplings. They are equipped with a male G 3 /4 nose piece, which is intended to be screwed directly into the workpiece. As an alternative, they can be used in combination with the appropriate SKF hydraulic accessories.
