Cast iron gear pumps for enhanced valve steering

1st Quarter 2018 Hydraulic systems & components

Hydraulic and Automation Warehouse (HAW) has introduced the latest Salami Group 2 (PG20) range of cast iron gear pumps. These are highly suited for mining, agriculture and forestry applications. They are dust-resistant and explosion-proof and are more compact than their predecessors.

Housed in a front mounting flange and rear cover, pumps in this range boast a one-piece drive shaft construction and feature double shaft seals on pumps with reinforced inner shaft seals for motors. They are available with displacements from 16 to 26 cm2/rev and come with the option of shafts, flanges and ports as per European and American standards. All have two flange mounting styles, five shaft types and the porting is the standard BSP/SAE threaded/Bosch square and diamond porting.

In addition to extended product longevity gained from the cast iron composition, their high carbon content and low static discharge capabilities secure their explosion-proof status. The small dimensions are achieved by installing the gear set, gear support bushings and suction and delivery ports within the main body and the design satisfies a variety of OEM manufacturing designs.

Pumps in this range have a maximum starting viscosity of 800 mm2/sec, minimum operating fluid viscosity of 12 mm2/sec and suggested fluid viscosity range of 17 to 65 mm2/sec. Double shaft seals are used, with nitrile seals as standard and Viton seals for high temperature applications. The fluid operating temperature range varies from -25 to 85°C and -250 to 110°C with Viton (FPM) seals.

How to protect against water hammer
SA Gauge Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
