Main technical features of Movitec VF series vertical multi-stage centrifugal pump

Product Overview

This vertical multi-stage high-pressure centrifugal pump features a segmented design with concentric suction and discharge ports of identical nominal diameter (pipe-type configuration), operating in direct-drive mode. It is equipped with a KSB SuPremE magnetless synchronous reluctance motor (IE4/IE5 energy efficiency rating per IEC TS 60034-30-2:2016 standard), except for the 0.55 kW/0.75 kW model with 1500 rpm speed that incorporates permanent magnets. The pump is driven by a KSB PumpDrive 2 or KSB PumpDrive 2 Eco speed control system with a rotorless position encoder. Its mounting points comply with EN 50347 standards, while the housing dimensions meet DIN V 42673 (07-2011) specifications. An ATEX-rated version is available upon request.

2. Design

The Movitec VF pump features a modular design, primarily comprising the pump base, hydraulic components, outlet cover, mechanical seal, motor bracket, adapter flange, and motor.

The Movitec VF series is a non-suction, multi-stage vertical high-pressure centrifugal pump with inlet and outlet pipes of identical nominal diameter arranged in opposite directions.

Product Features

It is widely used in industrial, building and water engineering, and power industry.

The range of options for materials, drive mechanisms, connections, and sealing types is extensive.

high energy efficiency

high reliability and security

1: By optimizing the design of pump components and hydraulic systems, the Movitec VF pump outperforms competing products with higher efficiency and a competitive NPSHr value, delivering enhanced operational stability to customers.

2: All liquid-contacting components are made of stainless steel, which extends the pump's service life and enhances the safety of the pumped medium.

3: The pump shaft with two flat surfaces facilitates optimized torque transmission. The number of start-stop cycles per minute is not restricted by the pump body design. Suitable for stringent operating environments.

4: Movitec VF has two drainage bolts on the inlet and outlet sides of the pump housing, which can completely drain the medium at the bottom of the pump body and can also be used as a bypass pipe. It is easy to maintain and highly reliable.

5: Movitec VF comes with a standard Easy Access mechanical seal, a type of unbalanced bellows seal. If the drive unit exceeds 5.5kW, the motor does not need to be disassembled.

6: The KSB company's IEC high-efficiency motor (IE3) achieves 3.5% energy savings compared to EFF2 or IE2 models.

7: Movitec VF features self-lubricating tungsten carbide sliding bearings, a torsion-resistant pump housing, and sealed O-rings, ensuring enhanced reliability and durability.

8: All components are imported from KSB's Dutch factory in Europe, ensuring customers enjoy premium materials and craftsmanship.
