Wangen Progressive Cavity Pumps
Engineering Brilliance
For New Zealand industries where abrasion, fibrous content, and maintenance costs are key concerns, Wangen Progressive Cavity (PC) pumps offer a economically and technically superior solution.
Their robust mechanical design with bearing isolation, durable cardan joints, and hardened rotors contribute to exceptional wear life. Wangen PC pumps also run at lower RPMs, resulting in less heat, vibration, and ultimately, wear. The quick-change cartridge seals further reduce downtime during maintenance, enhancing overall efficiency.
Blockage-free operation
Wangen’s fully encapsulated cardan joint has needle roller bearings and a protective sleeve. It is engineered for continuous, blockage-free operation in abrasive and fibrous media - minimising wear and eliminating common failure points associated with conventional pin joints. Wangen has also integrated a separate bearing housing between the pump and gearbox to isolate axial and radial loads from the drive, again, significantly reducing wear and extending service life.
- Fully sleeved universal joint with needle roller bearings designed for long-term durability
- High power transmission designed to maintain efficiency at high pressures.
- The joint easily handles radial and thrust loading.
Maintenance-free Mechanical Seal
Wangen's LWD Cartridge mechanical seal offers a compact, pre-assembled design that enables fast, tool-free replacement. Pump reliability is improved and downtime reduced due to minimal leakage and wear. The net result is a highly efficient and user-friendly sealing solution, ideal for demanding applications .
- Pre-assembled, oil-lubricated mechanical seal in a sealed chamber.
- Prevents ingress of solids and simplifies replacement.
- Simple replacement (a single piece).
- Ideal for abrasive applications.
Overview of our Wangen Progressive Cavity Pumps
Wangen produces an extensive range of hopper feed pumps for slurries and pastes with high solids content (KL-R Series) and dewatered sludge (KL-RU, KL-RQ, KL-RS and KL-R Triplex models).

FAQ
At Prime Fluid Management, we understand that every fluid management challenge brings unique considerations. Here, you’ll find clear, practical answers and expert guidance to help you maximise uptime, achieve regulatory compliance, extend equipment life, and implement the most effective solution for your site.
A slurry pump is designed to move mixtures of liquid and solid particles where the liquid component helps the material flow. It is built with abrasion and corrosion resistant materials and a robust design to handle the wear from suspended solids.
A sludge pump is designed to handle much thicker and stickier material known as sludge which has a higher solid content. These pumps often use positive displacement or slow moving mechanisms to avoid clogging and manage dense viscous fluids.
