What is the CPC Sanitary Centrifugal Pump made for?

The CPC Series of Centrifugal Pumps is designed specifically for use within the Food and Pharmaceutical industries with a heavy emphasis on robust design, optimal cleanability, efficiency, low maintenance costs and simple maintenance. The range consists of 4 set sizes, CPC 160-210-260-310 with a capacity range up to 400m/hr and 9 Bar in 50 Hz and 500m/hr and 13 Bar in 60 Hz and standard and 40 Bar for the CPC-HD units for high-pressure applications such as pressure boosting or reverse osmosis.

All liquid contact parts are in compliance with EHEDG standards and manufactured from cast Stainless Steel AISI 316L or AISI 316L Mo+Ni or Hastelloy C22 upon request for increased corrosion resistance with a surface roughness of 0.8 as standard (0.5 on request). The open or star impellers, which are dry mounted to the shaft by means of O-Rings, are also fitted with pressure relief holes to ensure optimal cleaning of the shaft seal and chamber. The O-Rings ensure that there is minimal liquid contact with the shaft whilst cleaning the contact faces at the same time.

There is minimal clearances between the impeller and the back casing to ensure high efficiencies and pressures whilst retaining its solids handling ability up to 10 mm. Units can be supplied close coupled in KAM, KAV & KAC designs with B3 or B5 motors or with pneumatic, diesel driven or hydraulic motors in their IG & IGH forms. Various Mechanical Sealing & O-Ring options, as well as drain connections and heating jackets, are also available on request.

Features

Mechanical Seal

mechanical seal

All mechanical seals are specifically designed for use with the CPC range according to DIN 24960 and are fitted with EHEDG / FDA compliant O-Rings. They feature a 2 pin construction so that they rotate with the impeller. They are available in the following material combinations:

  • Carbon to CrMo-steel

  • Carbon to silicon carbide

  • Carbon to ceramic

  • Hard metal to hard metal

  • Silicon carbide top silicon carbide

  • Tungsten carbide to tungsten carbide

Internal Mechanical Seal

The mechanical seals are available with EPDM, Viton, Perbunan and Teflon "O"-rings.

Internal Mechanical Seal /Internal Mechanical Seal w. Quench

A quench is applied when a constant pressure-free flush to prevent fouling of the mechanical seal is required due to the product being pumped. External Mechanical Seal /External Mechanical Seal with Flush

A Flush is applied when a considerable under-pressure is present on the suction side or when a constant flushing of the seal is required. The pressure of the flushing fluid must always be higher than the discharge pressure.

Balanced Stub Shaft Design

Balanced Stub Shaft Design

All CPC-ZA Sanitary Self Priming Centrifugal Pump are fitted with a balanced stub shaft design with features a conical shaft end without keyway and dry mount EHEDG / FDA compliant O-Rings. Grub screw attachment to the motor shaft enables easy assembly and disassembly during maintenance procedures.

When mounted, the open impeller has pressure relief holes to ensure optimum efficiency and cleaning of the mechanical seal which is attached to the impeller via its 2 pin construction.

High-Pressure Casing

High Pressure Casing

The cast stainless steel AISI 316L, machined from a solid block, casing can withstand system pressures up to 25 bar as standard and 40 bar upon request (CPC-HD). It has also been machined to provide optimal cleanliness by eliminating any dead space areas for bacterial build up to be in line with EHEDG standards.

Optional Heating Jacket

Optional Heating Jacket

All models can be fitted with an optional heating jacket to maintain fluid temperature whilst being pump and is generally used when transferring for higher viscosity edible oils.

Variations & Configurations

  • Depending on the area of the application the following design variants are available on demand:

  • Stainless Steel Sanitary Centrifugal Pumps designed with In-Line connections. This makes it possible to install the pump directly into the pipework.

  • Stainless Steel Centrifugal Pump for whey curds. Designed with tangential outlet. The pump was especially designed for pumping of soft and vulnerable media. This pump is therefore limited to a maximum operational speed to 1000 rpm. It is only available in construction sizes 29088 & 36088.

  • Stainless Steel Sanitary Centrifugal Pump designed with radial outlet (the outlet opening of the pump is located directly above the central axis of the suction opening).

  • CPC-ZA: Self-Priming variant of the CPC Series. Capacity range up to 300m/hr & 9 Bar in 50 Hz and 350m/hr & 13 Bar in 60 Hz. Not EHEDG Certified however sanitary in construction. ATEX rated.
