Self-Priming Pump(CIP Pump)

Self-Priming Pump is a hygienic side-channel design sanitary pump, it is applicable by food processing, biopharm and chemical industries. Self-priming pump is specially designed for pumping materials what containing air or gas, and it can be also be used for negative suction with prior priming as well as with filtration equipment. Wellgreen self-primping pump can be used for wine, fine oil, syrups, volatile products such as alcohol, acetone and other solvents, or other materials which temperature close to boiling point. However, the mainly using field of self-priming pump is for CIP returning.

 

Design and Features

• Cover of motor is made by cold-formed plate.
• Stainless steel investment casting inlet-body and impeller.
• Mechanical sealing prevents contacting between the springs and the pumped fluid.
• Stainless steel support
  .

Materials

• Wetted parts: AISI 316/304
• Other parts: AISI 304
• Gaskets (standard): EPDM(FDA)
• Mechanical sealing(standard): C/SiC/EPDM
• Internal surface finish: Polished
• External surface finish: Sand-blasting

Technical specifications

• Max. flow : 30m³/h 132GPm
• Max. head : 30H(M)
• Max. pressure : 3Bar/43PSI
• Max. operating temp. : 120°C/248°F
• Max. revolving speed. : 1750 min
• Max. suction head : 8m/22ft

Operating Principles

The impeller is housed between the inlet body and the venture casing, it rotates in conjunction with the pump shaft. The rotation of the impeller and arrangement of the side channel, creates a negative pressure inside the inlet body, 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 impeller casing.

Options

• Mechanical sealing in SiC/SiC
• Gaskets in FPM(Viton) and PTFE
• Inlet&Outlet Connection: Tri-Clamp, Threaded, Flanged to DIN, SMS, 3A, RJT etc.
