CHARACTERISTICS The pump drives range of equipment allows a single or a multiple of pumps to be driven from a single prime mover. Single pump drives allow a pump to be close coupled to a diesel engine that has a flywheel and flywheel housing in accordance with SAE standards (non standard can also be accommodated). Supplied in a kit format consisting of a bell housing fully machined to suit the particular pump mounting and a flexible coupling to suit the engine flywheel and particular pump shaft. Multiple pump drives allow two or more pumps to be driven from a single prime mover. Available in...

Pump drive type When selecting a suitable AM unit, it is necessary to consider the input power limits set below: (1) Stationary industrial applications, without cooling system for pump drive. (2) Mobile or intermittent applications, without cooling system for pump drive. (3) Stationary industrial applications, with Technodrive cooling system. Maximum continuous power may increase by using a stronger cooling system. Columns 1 and 2 indicate the maximum continuous and intermittent power for where it is unnecessary to have a pump drive cooling system. The values shown are only indicative in so far...
