Joint Connection: Comprises five components, featuring wear-resistant, hardened, and replaceable parts for easy repair.
Universal Joint Sleeve: Protects grease-filled joints from product penetration under maximum vacuum or pressure.
Stator and Rotor: The stator is flexible and fixed on one side, while the rotor is made from wear-resistant, corrosion-proof materials with additional surface treatment.
Shaft Sealing: Single-acting mechanical seal located inside the pumped product.
Drive: An electric motor directly flanged to the pump, with options for geared motor or variable speed drive.

Applications
Wobble pumps are used across various industries, including agriculture, ceramics, chemical, construction, food and beverage, mining, oil production, pharmaceuticals, and more.

Advantages

Overview of ranges Pumps of the BW range are very easy to handle and economical. In contrast to conventional progressive cavity pumps, they have only one joint, which saves costs and reduces downtime when replacing spare parts. The wobble-stator pump is also space saving because the lantern has been dispensed with – the drive is flanged onto the pump directly. 5 Range BW
