Pumps are critical for many construction, utility and municipal applications. As such, pump manufacturers are continually making enhancements to their product lines to offer a variety of benefits. We've asked several leading suppliers to highlight their product lines and provide a brief summary of the newest technologies.
What types of pump products do you offer for construction and other heavy-duty applications?
Godwin: Our flagship automatic priming, centrifugal Dri-Prime pump is capable of flows to 13,500 gpm, heads to 615 ft. and solids handling to 5 in. in diameter. Available in sizes from 2 to 24 in., these pumps provide suction lift capability to 28 ft. and continuous uninterrupted operation, even during intermittent dry suction conditions.
Our Sub-Prime electric and Heidra hydraulic submersible pumps are available from .5 to 90 hp in dewatering and trash-handling models. The line is designed for sewer bypass pumping jobs requiring a suction lift greater than 28 ft. These hydraulically driven submersible pumps are available in 3- to 12-in. sizes and are built for moving sludge and solids-laden fluid.
Gorman-Rupp: We offer self-priming centrifugal solids-handling and high-head pumps (electric and motor driven); priming-assisted centrifugal solids-handling and high-head pumps (electric and motor driven); and dewatering and solids-handling submersible pumps (electric and hydraulic).
Griffin Pump & Equipment: Griffin manufactures non-clog pumps with large clean-out ports for high flow required by large sewer bypass pumping applications. Our silent pumps for low-noise environments produce only 70 dB at 23 ft. Our electric submersible pumps feature stainless steel motor housings, impellers and impeller casings to quickly remove water from confined work areas.
Our high-pressure, high-flow, high-head capacity jet pumps are now available with Tier III engines for better performance and reduced emissions. They are capable of delivering flow over 1,400 gpm and head conditions up to 900 ft.
ITT Flygt: We offer heavy-duty portable electric submersible pumps that can withstand the severe demands of construction sites and mine dewatering. In addition, we furnish a complete range of submersible wastewater and slurry pumps and axial flow propeller pumps, as well as mixers, monitoring and control systems and SCADA devices.
Thompson Pump: We sell and rent heavy-duty portable pumps ranging in size from 2 to 18 in. for use in public works, municipalities, construction, agriculture, dewatering, mining, sewer/lift stations and water/wastewater.
We engineer wet prime trash pumps; dry prime trash pumps with compressor- or vacuum-assisted priming systems; sound-attenuated pumps; utility trash pumps; diaphragm pumps; hydraulic power units with submersible pump ends; rotary, vacuum and piston wellpoint pumps; and high-pressure jet pumps.
We also offer accessory hoses and piping, as well as engineering services and special applications consulting for wellpoint, bypass or multiple pump systems.
What are the most recent advances that have been incorporated into your pump designs to maximize pumping efficiency and/or accommodate jobsite conditions/requirements? What are the benefits to end users?
Godwin: Our rental business generates feedback that allows us to consistently refine designs and materials.
Our HL Series extreme high-head pumps with single-stage impellers have benefited from this vertically integrated relationship. Contractors can now use our HL pumps, which are capable of heads to 615 ft. and flows of 2,500 gpm, to jet in piles for bridge construction. One impeller means there are fewer parts to maintain or wear out compared to the previous multi-stage pumps used for pile jetting.
We have also begun utilizing GPS and telemetry in our Dri-Prime pumps through our PrimeGuard Controller. Pump operators can remotely monitor pump performance and operation via the use of an external communication port. Fully programmable controls start and stop the pump with no operator intervention required.
