A gear pump is a kind of rotary pump and is defined as a positive displacement pump. Gear pumps are roughly classified into external and internal gear types. This pump is a external gear type pump. Its operating principle is that the fluid in the space between the valleys of the gears and the casing is forced out to the opposite side when the two gears rotate.
The gear pump incorporates an internal bypass valve which can be used to relieve pressure from the high pressure discharge side of the pump to the suction side. The relief valve works by using a plunger and spring arrangement. When the pressure exceeds the pressure of the spring, the plunger is displaced and liquid is allowed to circulate to the suction side of the pump.
To adjust the internal relief valve, user must first remove the adjustment valve cover. Using an Allen key, turn the bolt head clockwise to increase the spring pressure and increase the pressure required to open the bypass valve. Turning the Allen key anti-clockwise reduces the spring pressure and allows the internal relief valve to open at a lower pressure. The adjustment cover should be refitted after adjustment.
