INSTALLATION INSTRUCTIONS

Installation
The mechanical connection between the pump and the motive power source may be made by means of a pul-
ley and belt, with a drive shaft, or through a direct flanged connection to the motive power source.
The crankshaft may turn in either direction.
The water connection between the pump and the machine circuit must be made using hoses of suitable diam-
eter, in all case no less than that of the pump fittings, securing them to the fittings using good quality clamps.
The intake hose must be coil-reinforced to prevent restrictions.
The machine intake circuit must be fitted with a filter having suitable capacity for the pump delivery rate and
must be designed to generate a vacuum of no more than - 0.25 bar. This value can be measured by connecting
a vacuometer to the pump intake fitting.
The rated pressure of the delivery hose, fittings and clamps must be no less than the maximum rated pressure
of the pump. Replacing the intake and delivery fittings provided on the pump by the manufacturer with small-
diameter alternatives may reduce the pump's performance and annul the warranty.
Mounting the pump
The pump must be installed on a horizontal surface with no flexible components between it and the mounting
surface.
The illustration shows the maximum permitted pump installation angle beyond which proper lubrication of
the crank mechanism is not ensured.
max 5°
Fix the pump by screwing the pump support onto the base of the machine with suitable screws, tightening
appropriately.
