Hygienic Submersible Centrifugal Pumps

Hygienic Submersible Pumps

Packo ICP-IM Vertical Process Cantilever Pumps

Packo Stainless Steel Submersible Pumps are designed for installation in a sump or tank, having only the casing and impeller submerged. They are used in applications with liquids which are difficult to seal with a mechanical shaft seal and when no support bearing inside the liquid is allowed, such as abrasive slurries, frying oils and metal finishing coatings.

ICP-IM pumps have been designed to utilise the standard Packo ICP pump hydraulic components. They are available with closed, open or vortex impellers to meet the requirements of a wide range of different applications.

Construction

Vertical Process Cantilever Pumps, specially developed for liquids which are difficult to seal. Corrosion resistant, leak proof and maintenance free.

• Standard IEC motors: Pumps can be factory fitted with motors with special characteristics (special voltages, integrated frequency converter etc.)
• Optional base plate in stainless steel
• Cantilever shaft: Tapered design. The shafts are machined and finished throughout the entire length so that the total run out at the impeller bore is minimal
• High strength column: Support pipe rigidly and maintains alignment between motor and casing. Protects pump shaft
• No bottom bearings. No oil or water pipes required to lubricate submerged bearings
• Seal less pump: There are no seals, submerged bearings or bushes exposed to the product, thereby reducing downtime and operating costs. The pumps are capable of operating dry with no adverse effects. Renewable shaft “labyrinth” sleeve minimizes blow-back of liquid around shaft. Provides added pump shaft protection against abrasives
• Impellers in 316 stainless steel. ICP3-IM with closed impeller; ICP2-IM with open impeller (not shown); IFF-IM With (semi-) open recessed impeller for liquids containing solids (not shown)
• Optional outlet pipe

Electropolished - Resistant to Corrosion and Product Adhesion

All stainless steel parts are electropolished.

• Electropolishing leads to an increased corrosion resistance due to the higher percentage of chromium and nickel at the surface
• Electropolishing also leads to extremely low micro-roughness, resulting in an increased resistance to the adhesion of products
• Electropolishing strongly reduces the possibility of tension corrosion

Model Variants

IMXL Vertical Cantilever Pump

• IMXL – Extended length for deeper sumps/longer reach. Maximum length = 1.5m
• Same hydraulics as ICP2, IFF2 and ICP3 pump range
• With bearing bushing in SiC/Ceramics (CrOx) or duplex/Graphlon
• Maximum speed up to 3000 rpm

IMO External Vertical Cantilever Pump

Same general construction as the ICP-IM pump range but is mounted outside the tank where restrictions prevent submersing the pump direct into the product.

Additional Connections

1. A separate bypass connection is provided to return the seal overflow back to the tank
2. An optional cleaning connection can be provided to CIP the inside of the tube
