Variable-speed pumps

Rather than constantly running at full speed, Intelligent Variable-Speed (IVS) pumps use variable-speed technology to vary flow to meet actual system demand. IVS Sensorless pumps match system demand without the use of sensors and are programmed with pre-defined control curves that automatically adjust speed and pressure to match system load. The control curves are site-adjustable, letting installers match installation requirements. — Armstrong Pumps Inc.

Water-source heat pumps

Ranging in size from ½ to 6 tons, EP Series commercial water-source heat pumps can be used in geothermal applications when equipped with an extended-range option. A four-sided filter rack and foil-faced fiberglass insulation are standard. An optional heavy compressor blanket is available for units installed in mission-critical locations. — FHP

Multistage pumps

Suited for a variety of commercial and industrial applications, e-SV stainless steel, vertical multistage pumps feature a hydraulic design and efficient motor. The mechanical seal is replaceable without the need for pump disassembly, and the “O”-ring seat is designed to allow disassembly of the outer sleeve. — Goulds Pumps, a brand of ITT Corp.

Available in cast iron and stainless steel, Model UPS50-60 SuperBruteXL circulators feature a three-speed wet-rotor design. The rotor's shaft and bearings are constantly in contact with, and cooled by, surrounding circulating water. The wet-rotor design doesn't require a fan, so the unit operates quietly. A sealless and oilless design minimizes maintenance. — Grundfos Pumps Corp.

High-solids-content pumps

Moyno 2000 CC pumps transfer abrasive, high-solids-content materials. They are designed for municipal and industrial applications in which close-coupled configurations are preferred, but a gear joint drive is needed. The pumps feature a sealed gear-type universal-joint drive train and optimized rotor/stator pumping-element geometry. — Moyno Inc.

Water-to-water heat pumps

Compatible with closed-loop and ground-loop water-source-heat-pump applications, Virtual Moveable End Cap (VME) Water-to-Water Heat Pumps are modular and can be expanded to meet future building needs. Utilizing a combination of 15-, 20-, 30-, 50-, and 70-ton units, 15- to 600-ton chiller-heater systems can be created. — Multistack

HVAC pumps

With flows of up to 2,500 gpm and heads of up to 400-ft TDH, EnviroFlo HVAC pumps are available in frame-mounted and close-coupled models. The pumps feature a back-pullout configuration for ease of access and maintenance. The bearing housing mounts directly to the pump volute to save space and provide proper alignment. — Patterson Pump Co.
