HVAC-system pumping; general purpose pumping; industrial/process pumping (water or glycol based)
Pipe-mounted 2-pump unit with integrated intelligent controls for space-saving installation, superior energy performance, and duty/standby operation. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations.
  • Cast or ductile iron casing
  • Cast iron or bronze impeller
  • Sintered silicon carbide mechanical seal

Performance range
Up to 1250 USgpm (80 L/s) flow and 400 ft (120 m) head
250oF (121oC)
Power Range
1 hp to 100 hp (0.75 kW to 75 kW)
2" to 6” (50 mm to 150 mm)
Lowest installed cost
Vertical In-line design eliminates the need for inertia bases, housekeeping pads, and flex connectors and reduces piping requirement
2-pump casing for reduced footprint
Integrated intelligent controls eliminate procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensors
Superior energy performance qualifies for significant cost recovery under utility and government rebate programs
Lowest operating cost
Integrated intelligent controls – combined with perfect component match-up and tuning – for up to 75% in energy savings over traditional constant speed and variable frequency operated pump installations
Shorter pipe runs for reduced system friction
Vertical In-Line configuration allows less disruptive pump service (casing stays in place)
Lowest environmental cost
75% decrease in energy consumption reduces operational greenhouse gas emissions at equal ratio
Elimination of inertia bases, housekeeping pads, flex connectors and superfluous piping avoids all procurement related environmental impacts (material, energy, carbon)
Equipment downsizing mitigates environmental impacts associated with procuring unnecessarily large equipment
Integrated Twin design packs and ships more economically for less packaging waste compared to loose component shipping and assembly
Lowest project and operating risk
Integrated intelligent controls for fast and easy commissioning as well as reduced radio frequency interference/ improved electromagnetic compatibility
Single source-responsibility for optimum design and field support
Twin design for full redundancy in case of emergency or routine servicing
