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.
It depends on the fluid, temperature, viscosity, and how the tank and pipework are laid out. A flooded suction setup is usually the most stable option for consistent performance, especially with higher viscosity oils, because the pump is always supplied with product.
If the pump needs to draw from a lower level or from a longer suction line, suction lift and self priming capability become important. However, the setup needs to be sized correctly to avoid issues like poor priming, air ingress, or cavitation. If you share your suction conditions and duty point, we can recommend a pump type and configuration that suits the installation.
For fuel and oil applications, reliability often comes down to protecting the pump from pressure spikes and contamination, and selecting the right sealing arrangement. Depending on the pump type and duty, options can include an internal relief or bypass valve to protect against dead heading, and an inline suction strainer to reduce the risk of damage from debris.
Seal selection also matters for demanding services, with configurations such as double mechanical seals used on certain duties where additional containment or reliability is required. We can guide you on what features make sense based on the product, operating conditions, and site requirements.
To specify the right fuel transfer pump for a New Zealand site, we typically need the fuel type, required flow rate, temperature, and viscosity, along with suction conditions such as flooded suction or suction lift.
Once we have those details, we can confirm the most suitable pump type and configuration for your application – including options for heavier fuels where viscosity is higher.
