used in accordance with the instructions of the corresponding manufacturers.
- The aspirated liquid must not contain sand or other solid particles in suspension.
- The aspirated liquid must have viscosity and density characteristics similar to those of
water.
- The temperature of the liquid to be pumped must be between 5°C (41°F) and 38°C
(100°F).
- Any other use is prohibited, except in writing from the Technical Service.
4.4.2. Pump inlet and outlet
The inlet mouth of the liquid to be pumped, also called suction or supply, is generally larger in
diameter than the outlet mouth, also called impulsion.
Warning
The Pump Inlet and Outlet can NOT be reversed with each other.
4.4.3. Feed conditions (suction)
Check that the power line is correctly connected and that it meets the following requirements:
- Have, at each of its points, a minimum internal diameter equal to the internal
diameter of the inlet of the Pump.
- Be perfectly hermetic in order to avoid harmful air infiltrations.
- Not present, throughout its length, any strangulation or narrowing of the ducts.
- Avoid all kinds of turbulence near the pump inlet and the feed tank.
- Any filter must have a minimum capacity of at least 2 times the flow rate of the
Pump and must not cause bottlenecks or pressure drops. The recommended
filtration degree is 32 ÷ 50 and its efficiency must be maintained by cleaning the
filter every time it is necessary.
- Maximum allowable suction pressure: 0.5 bar (7 PSI).
- Maximum allowed negative pressure in suction: -0.2 bar (-3 PSI) [-6 inch. Hg].
