SKF THAP 030E 150E 300E 400E
1. Application
1.1 Air-driven oil pumps THAP 030E and THAP 150E
The THAP 030E is designed to have an oil outlet pressure of 30 MPa (4 350 psi).
The THAP 150E is designed to have an oil outlet pressure of 150 MPa (21 750 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.
1.2 Air-driven oil injectors THAP 300E and THAP 400E
The THAP 300E is designed to have an oil outlet pressure of 300 MPa (43 500 psi).
The THAP 400E is designed to have an oil outlet pressure of 400 MPa (58 000 psi).
Depending on the maximum oil pressure required, 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.
2. Description
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. Complete sets consisting of the air-driven oil pump or injector are shown in
section 6.
