1. Application
The SKF High Pressure Pump, THHP 300, is
intended for the mounting and dismounting of
pressure joints using the SKF Oil Injection Method.
This includes such applications as couplings, gears,
pulleys, flywheels and SKF OK Couplings; where
the surface pressure is often in the region of
250 N/mm2 (250 MPa, 2500 bar, or 36 260 psi).
The high pressure generated by the THHP 300
should not be used with standard hydraulic
cylinders, jacks and other such equipment, which
generally require 70 N/mm2 (70 MPa, 700 bar,
or 10 150 psi).

2. Description
2.1 General description
The SKF High Pressure Pump THHP 300 consists
of a high-pressure pump with a 0-300MPa
(0-43,500 psi) pressure gauge mounted and
includes a high pressure hose and a quick
connection coupling. A loose quick connection nipple
(THPN 300-1) is supplied and can be attached to
the G1/4 and G3/4 conversion nipples included, to
suit the application.
The design allows oil to be automatically
returned to the reservoir, once the pressure is
released, minimizing the risk of oil leakage to the
environment.
