SIHI ISOchem Pump CBE

SIHI ISOchem Pump CBE is a horizontal, single-stage volute casing pumps with dimensions to DIN EN ISO 2858. They meet the technical requirements of EN ISO 5199. It is a modular configuration of either bare shaft end or close-coupled design. This modular process pump consists of hydraulics with closed impellers. Due to the modular configuration, the pumps can be used in a bare shaft or close-coupled configuration. Shaft sealing options are single or double acting mechanical seals, magnetic drives or canned motor designs. The benefits are the interchangeability of the back pull-out assemblies and a reduction of spare parts costs.

 The SIHI ISOchem Pump CBE range of pumps meet the requirements on custom-built solutions in the process industry, in the following areas:

• Chemical
• Food processing
• Plant engineering and construction
• Pharmaceutical
• Petrochemical
• Paper
• Plastic

Technical Data:

• Flow rate: max. 650 m³/h
• Head: max. 150 m
• Speed: max. 3600 min-1
• Materials: Cast iron, cast steel, stainless steel, Hastelloy, duplex
• Temperature: max. 400 °C Casing pressure: max. 25 bar
• Shaft seal: Mechanical seal or magnetic coupling Dimensions of according to DIN or ANSI flanges: (see flanges)
• Direction of Rotation: clockwise, when viewed from rotation drive end

The SIHI ISOchem Pump CBE is a modular configuration of either bare shaft end or close-coupled design. Shaft sealing options are single or double-acting mechanical seals or magnetic couplings. The benefits are the interchangeability of the back pull-out assemblies and the reduction of spare parts cost.

Benefits:

• Temperature range: -40°C up to +400 °C. No cooling required.
• Impeller secured with key and nut – no possibility of damage if the rotation is incorrect.
• An integral strainer is standard for the reliable handling of solids.
• Robust product lubricated SiC bearing assembly – reliable even under adverse operating conditions. Radial and axial lubrication grooves improve dry running properties.
• Deep drawn Hastelloy containment shell – low drive losses, no welding used, very high-pressure rating.
• No O-rings in contact with pumpage – no compatibility or purity issues.
• Provision for PT100 is standard for temperature monitoring and dry run protection.
• Pumps are close-coupled as standard. No time-consuming alignment is required. Alignment of pump and motor is unaffected by temperature swings.
• Enclosed impeller with balance holes is standard – effects of axial thrust are reduced for increased reliability.
• Built-in safety clearance prevents rupture of containment shell in the event of bearing failure.
• Large installed population base.
