DESCRIPTION OF THE PUMP

HYDRAULIC PART
Fig. 02
The pumps are built with high quality materials, worked and handled by technologically advanced
machines.
The pumps consist of three basic parts (Fig. 02):
• Mechanical Part
• Pumping Part
• Hydraulic Part
A. The Mechanical part consists of a cast iron body inside which the following are housed:
- Crankshaft, pressed and treated
- Roller bearings
- Connecting rods with thin-walled bearings with high mechanical resistance and a high load capacity
- Guide pistons with antifriction surface treatment
Oil shaking lubrication is used for the whole unit.
B. The Pumping part consists of:
- Ceramic pumping elements
- High quality, long-life pressure gaskets
- Bronze gasket supports
C. The hydraulic part consists of:
- Head treated with a coat of nickel
- Easy-to-inspect intake/delivery valves in stainless steel.
OPERATION
The piston displacement pump requires a source of energy able to supply the energetic increase
necessary for the fluid and to drive the whole link mechanism and any other auxiliaries.
The main energy sources for this type of pump are electric motors and internal combustion engines.
The reciprocating motion of this pump's pistons creates vacuum inside the cylinder - during the
downstroke motion, opening the intake valves and drawing the fluid back inside, while during the
upstroke motion (compression) the over pressure that is created causes the outlet (delivery) valves to
