ASPIR

Product catalog summary

Application
The Aspir pump is a sanitary side-channel self-priming pump designed for the food-processing, pharmaceutical, and chemical industries. It is suitable for pumping products containing air or gas and can be used for negative suction with prior priming and in filtration equipment. It is ideal for pumping wine, oil, syrups, volatile products like alcohol and acetone, and products near boiling point, with its primary use being CIP return.

Operating Principle
The pump's impeller is positioned between the suction casing and the diffuser, rotating with the pump shaft. This setup creates negative pressure inside the suction casing, generating suction force. The fluid gains kinetic and pressure energy, propelling it through the discharge casing.

Design and Features
The Aspir pump range includes centrifugal pumps made from cold-formed stainless steel discharge casing, cast stainless steel suction casing, diffuser, and lantern. It features a star-shaped fixed impeller and an external mechanical seal to prevent spring contact with the product. The motor complies with IEC standards and is protected by a stainless steel shroud with adjustable hygienic legs.

Technical Specifications

Materials: Stainless steel AISI 316L for parts in contact with the product, AISI 304 for other parts, and EPDM gaskets.
Mechanical Seal: Silicon carbide rotary part, carbon stationary part, and EPDM gaskets.
Surface Finish: External matt, internal bright polish except for electropolished impeller.
Connections: DIN 11851, aseptic flange DIN 11864, CLAMP, SMS, with other options available.

Motor
The pump uses a triphasic induction motor with B5 flange and B3 legs, compliant with IEC standards, featuring 4 poles (1500/1800 rpm), IE-2 / IE-3 efficiency class, IP 55 protection, and F-class insulation. It supports various voltage configurations.

Options
Available options include a heavy-duty impeller, pump casing with drain port, different connection types, SiC/SiC mechanical seal, FPM and PTFE gaskets, motors with other voltages and frequencies, motors for explosive atmospheres, ATEX certification, and internal flow by-pass.

Dimensions
Detailed dimensions are provided for pumps with DIN 11851, Clamp, and SMS connections, specifying motor power, dimensions, and weight for various models.

Performance Charts
Performance charts illustrate the flow rates and head for different pump models (A-50, A-80, A-150, A-200) at 1750 rpm and 1450 rpm, showing the relationship between flow rate and head.

Catalog excerpts

Side Channel Pump I 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. I Operating principle The impeller is housed between the suction casing and the diffuser, it rotates in conjunction with the pump shaft. Due to this arrangement, the rotation of the impeller and the position of the side channel, negative pressure is created 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. I Design and features Aspir is a range of centrifugal pumps made of a cold-formed stainless steel discharge casing, cast sainless steel suction casing, diffuser and lantern, star-shaped fixed impeller, and an external mechanical seal that prevents any contact of the spring with the product. The motor complies with the IEC standards, it is protected with a stainless steel shroud made of stainless steel sheet and provided with the height adjustable hygienically designed legs.
