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

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.
Drainage submersible pumps remove or transfer unwanted water from a wide range of environments — from construction and mining sites to tunnels, basements, and flood zones. Designed to operate fully submerged, they eliminate the need for priming and reduce the risk of cavitation. Their ability to handle water with suspended solids ensures reliable performance in demanding conditions.
Yes — selected Grindex models feature advanced run-dry capability, with built-in thermal protection and a modular design that simplifies maintenance. This not only protects the pump during unexpected dry runs but also contributes to their reputation as one of the most reliable and durable drainage submersibles on the market - ideal for long-term, low-maintenance performance in demanding environments.
Drainage units focus on dewatering clean to lightly contaminated water and managing site water levels. Sewage units are engineered to move raw or solids-laden wastewater, with cutter, vortex or single-channel impellers to reduce clogging and pass larger solids.
