Your advantages

• The high overall efficiency through improved hydraulics and the use of IE3/IE4 motors enables energy savings
• Suitable for drinking water supply (compliant with ACS and UBA)
• Cataphoretic coating of all cast components for high resistance to corrosion and long service life (not available for drinking water versions)
• Universally usable thanks to standardised dimensions, a range of motor options and impellers made of different materials
• Easy maintenance thanks to user-friendly spacer coupling in back pull-out design
• High operational reliability thanks to improved impeller construction for pressure reduction

Design

Single stage, end suction back pullout centrifugal pump with axial suction, mounted on a baseplate.

Application

• HVAC and Fire Fighting
• Raw water Intake
• Boosting/Transport in water supply system

Equipment/function

• Deliverable single-stage low-pressure centrifugal pump in end suction design with coupling, coupling guard, motor and baseplate.
• With fabricated baseplate

Materials

• Pump housing and lantern. Standard: EN-GJL-250
• Impeller: Standard: EN-GJL-200; others on request
• Shaft: 1.4021
• Mechanical seal: AQEGG; other mechanical seals on request

Construction

• Single-stage, end suction back pullout centrifugal pump as baseplate pump with axial suction ports with flanged bearing brackets and axle fastening for flexibly coupled drives
• Spacer coupling (sleeve coupling) is standard; this provides the option of leaving the motor in position when dismantling the rotor unit
• Variant ...-P5 without spacer coupling (at reduced price, see price list)

Special features

• Energy-saving thanks to high efficiency through improved hydraulics.
• Cataphoretic coating of all cast components for high corrosion resistance and long service life.
• Universally usable thanks to standardised dimensions, a range of motor options.
