Project TIGER
The new generation of high pressure pumps from Hauhinco.
For absolute top performance in:
Mining■ Heavy Industry ■ Descaling
Project TIGER
The TIGER project is one of the most outstanding new development projects in Hauhinco‘s recent history.
We have incorporated the experience gained over decades by our employees in the mining, heavy industry and hot forming sectors around the globe into
the conceptual design.
A select, 15-strong interdisciplinary team of engineers and specialists have succeeded in creating a highly e cient, robust and maintenance-friendly Quintuplex pump from these concepts, using the latest development methods…

Quality, service, maintenance and design
Easy to access, Easy to maintain, Easy to exchange
Quality management
- Key components are procured via selected and audited suppliers from Germany.
- Materials are specifi ed via Hauhinco factory standards.
- Internal QA checks and certifi es the defi ned properties.
- Experienced assemblers ensure faultless assembly through self-inspection.
- Final acceptance on 1000 kW test bench with Test certifi cate.
Service
- Trained and licensed service personnel worldwide.
- Local stocking of wear and spare spare parts.
- Extremely short response times Technical questions.
E3 - Maintenance concept
- Easy to access, Easy to maintain, Easy to exchange.
- Cartridge design of the suction/pressure valves.
- Cartridge design of the plunger seal carrier.
- Separate dismantling option for each individual plunger drive.
- Access to the crankshaft drive without draining the oil.
- External access to all RWDRs and wipers.
- Complete maintenance without lifting tools or special tools.
Design
- New look for the Hauhinco Quintuplex pump range.
- Integration of functional elements into the housing design e.g. suction channel.
- Accessibility of the crank shaft.
- Consistent implementation of the E³ concept.
