2. DESCRIPTION OF THE PUMP
The pump is of robust construction, with a high strength light alloy casting body, or a sheet steel body, and a piston in lapped
steel.
The pump unit is made up of a cylinder in which operates a piston with an oilproof seal; a spring returns the piston to its start
position.
The pump must be provided with a three way electrical or mechanical distribution device, that is: line-cylinder-discharge.
The duration of the command impulse must not be less than 3 seconds.
The release (in the discharge position) must not be less than 10 seconds.
The useful capacity means the sum of the values of the applied valves.
The expansion of flexible tubing utilised in the system will reduce the useful capacity.
