4. General Information
4.1. DESCRIPTION
The ASPIR pump has a compact construction, monoblock and vertical aspiration and impulse.
The ASPIR pump is made of a cold-formed stainless steel discharge casing, suction casing, diffuser and lantern
built by stainless steel investment casting, star-shaped fixed impeller and an external mechanical seal that
prevents any contact of the spring with the product.
The standard IEC motor of type IM B35 is protected by a stainless steel shroud and provided with height
adjustable hygienic designed legs in stainless steel too.
4.2. OPERATING PRINCIPLE
The impeller is housed between the suction casing and the diffuser and it rotates in conjunction with the pump
shaft. This arrangement, together with the rotation of the impeller and the arrangement of the side channel,
creates a negative pressure inside the suction casing, which generates the suction force of the pump. At the
same time, the fluid receives energy in the form of kinetic energy and pressure energy, and this impels it
through the discharge casing.
4.3. APPLICATION
ASPIR pump is a sanitary side-channel self-priming pump suitable for use in the food-processing,
pharmaceutical and chemical industries.
It is specially designed for pumping products containing air or gas, and it can also be used for negative suction
with prior priming as well as in filtration equipment. It can be used to pump wine, oil, syrups, volatile products
such as alcohol, acetone and other solvents or products at temperatures close to the boiling point.
However, the main use of this pump is for CIP return.
For each type of pump, the hydraulic performance is given by the choice of impeller diameters and speeds. The
characteristic curves also show the power and NPSH requirements. The intended use of the pump is defined by
its characteristic curve and operating limits provided in the
s.
The range of application for each type of pump is limited. The pump was selected for a given set of
pumping conditions when the order was placed. Misuse of the pump or its use beyond the
operating limits may be dangerous or cause permanent damage to the equipment. INOXPA shall
not be liable for any damage resulting from the incompleteness of the information provided by the
purchaser (nature of the fluid, rpm, etc.).
