HNH Horizontal Series
Available in Extreme Duty (XD) & Severe Duty (SD) power frames
to best fit the hydraulic requirements of the application.
The HNH horizontal series is part of our HEVVY modular program, allowing you the flexibility needed for custom design to suit your application, saving you both time and money. The HNH series is available in several metallurgy options, offers three wet end designs as well as multiple seal options.
Available in Extreme Duty (XD) & Severe Duty (SD) power frames to best fit the hydraulic requirements of the application.
The hevvy modular program allows you the flexibility of coupling the pumping ends below with either the same or different hevvy drive configurations - be it submersible, cantilevers, or horizontal.
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.
WET END DESIGNS
The B Wet End is a hard wearing, heavy duty, closed impeller, slurry pump that comes standard in high chrome or CD4 MCU. The B is equipped with flow stabilizing vanes to increase efficiency and reduce turbulence and resulting impeller wear. Capable of handling Class 3 & 4 slurries and a 5” solids size. The B is able to reach high heads and a low NPSH R option is available.
The S Wet End is a fantastic semi-open, high efficiency, solids handling pump. This wet end is capable of handling Class 1, 2, & some Class 3 slurries. It boasts a special elliptical cut-water design which maximizes efficiencies and reduces wear. Available in ductile iron, High Chrome, CD4, Alloy 20, & more
The E Wet End has a fully recessed vortex impeller that permits an unobstructed passage of large solids. Fibrous material can also be handled without difficulty due to the natural flow of the fluid through the pump casing and the fact that the flow is virtually isolated from the impeller (only 15% of pumped liquid is in contact with the impeller). This pump is ideally suited for low shear applications. Available in ductile iron, High Chrome, CD4, Alloy 20, & more.
HNH SEALING
The HNH comes standard with packed box or choose a standard component mechanical seal or from a variety of our specially engineered slurry cartridge seal options below:
HYDRODYNAMIC SEAL
4 expellers/repellers that are capable of higher sealing pressure than typical single expeller/repeller design.
• Packing-less design.
• 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.
HNH SOLUTIONS
Hevvy Toyo has the ability to engineer, procure, and construct turnkey solutions that can be integrated within your system.
Solutions might include:
- Selection of appropriate motor starters and drives for optimal compatibility (Soft Starters, VFDs, and PLC control)
- Flow control and monitoring specifically for slurry pumps (control valves, flow meters)
- Piping, and complete seal plans (API Seal Plans)
