Companies Doing It Right!

Pumping mill scale for over 15 years for one of the largest american steel producers

5x HNH pumps have been operating since 2006 with no reported issues at one of the mills from one of the largest US steel producers; the HNH heavy-duty design with its high-chrome casing, wear plate, wear ring, and impeller have been proving every day for over 15 years that it is the right choice for mill scale applications.

Overcoming High Heads And Peak Flows In Underground Diamond Mines for a decade

In an underground diamond mine, 4x HNH are used in two independent systems (inline configuration) for a mine dewatering application. This arrangement allows for double flow in peak periods. The pumps have been running successfully since they were installed in 2005.

Pumping Out Aggressive Slurries In One Of The Largest Copper Mines on the planet

One of the largest copper mines in the world, located in the Democratic Republic of Congo in Africa is using these self-priming, diesel-driven, horizontal, HNH slurry pumps as utility pumps in an application in which low Ph, acidic slurries are being pumped out from sanded sumps and lagoons.

We’ve designed and pre-configured control panels so you can protect and get the most out our pumping solutions

Our HPD Series of direct on line start control panels are designed to ensure optimal use of your pumps which results in reducing the maintenance and total cost of ownership.

Our HPS Series soft start control panels allow for more frequent pump starts by offering a less harsh starting sequence that reduces in-rush currents which is safer and gentler on the motor and creates less heat build-up and reduces the chance of damage due to water hammer and cavitation effect during startup.

Our HPD and HPS Series control panels come pre-configured to provide the peace of mind that comes from knowing it was engineered to the highest safety standards.

THE MODULAR ADVANTAGES

  • Maximum Flexibility

    If your pump performance requirements change, simply change the pumping end to ensure you are always achieving maximum productivity and efficiency.

  • Cost Savings

    No need to buy a brand new piece of equipment when system requirements change. Just change the pump end. If you can standardize on the same pumping ends throughout your plant then you can greatly reduce the need for excessive spare parts inventory.

  • Increased Productivity

    Production is profit. When systems change the lead times of some custom drive units can not only be long but also expensive. If you can recycle your drive unit and simply change your pumping end you can get back into production quicker, cheaper, with less downtime required.

HNH SEALING Options

The HNH comes standard with a packed box or your choice of a standard component mechanical seal or from a variety of our specially engineered slurry cartridge seal options.

HYDRODYNAMIC SEAL

4 expellers/repellers that are capable of higher sealing pressure than typical single expeller/repeller design; featuring a packing-less design and an integrated flush port.

DOUBLE MECHANICAL SEAL

Extreme slurry cartridge seal design available with positive pressure quench plans.

SINGLE MECHANICAL SEAL

Severe slurry cartridge design with robust stationary single spring with higher tolerance for misalignment and shaft deflection.
