Fully lined pump for severe multi-stage applications which offers numerous ease of maintenance features
The HTP line represents the highest pressure-rated, large, lined pumps available with priority given to increased safety, wear life, and reliability.
The HTP is rapidly establishing itself as the dominant pump in the Canadian oil sands, providing an efficient and durable solution to long distance hydrotransport and tailings duties.

BENEFITS
Bearing assembly
- A large diameter shaft with reduced impeller overhang results in minimal deflection in the seal area and decreased load at the bearings.
Heavy-duty roller bearings extend mean time between rebuilds.
Only six through bolts and two clamping plates are needed to rigidly secure the cartridge housing to the one-piece base.
Cover / frame plates
- High strength ductile iron cover and frame plates support the abrasion resistance liner components.
- Industry leading 4000 KPa (580 psi) working pressure.
- Extensive reinforcing ribs minimize liner deflection and improve wear and performance characteristics.
- Double wall construction permits full wear utilization of the replaceable liners.
- Direct bolted discharge piping minimizes risk of flange failures common on hard iron unlined pumps.
Suction Cover
- separate fully removable suction cover facilitates access and replacement of impeller throatbush, and shaft sleeve without disturbing cover plate or discharge piping.
Liners
- Field replaceable liners are bolted to the cover and frame plates for positive attachment and ease of maintenance.
- Available in a variety of erosion and corrosion resistant metals and elastomers to maximize individual part life and extend preventative maintenance cycles.
- Hydraulic design of the volute liner has an optimized geometry to provide long wear life across a wide range of flows.
Impeller
- Specifically designed hydraulics emphasize solid passing capability, head generation, wear life, and efficiency to delvier overall outstanding performance
- Aggressive expelling vanes on the front shroud minimize recirculation and improve throatbush wear life.
- Optional expelling vanes on the back shroud reduce stuffing box pressure and axial loads to improve bearing life.
One-piece base
- Massive one piece base supports the cartridge bearing assembly and effectively transmits forces to the foundation.
- Base includes an external adjustment mechanism to maintain
