The Less-is-more Pump Primer

With increasing numbers of property owners looking to minimize maintenance expenditures

and maximize usable space, Pump Express system engineer Fred Hettinger has identified several paradigms of compact efficiency and innovation to illustrate the growing less-is-more trend in the pump industry.

Armstrong Pumps offers what amounts to a "two-fer" with their line of dualArm vertical in-line pumps. This innovative Armstrong commercial booster pump design incorporates two Series 4300 or 4380 pumps in a single casing. The Series 4302 dualArm is designed with split, spacer-type couplings so that the mechanical seals can be serviced without disturbing the pump or motor connections. The Series 4382 dualArm is the economical close-coupled version of this design. Both models feature swing discharge ports that hydraulically separate the casings to prevent recirculation when only one pump operates.

"The great thing about the dualArm pump," says Hettinger, Pump Express crack application engineer and a go-to Armstrong Pump supplier in New Jersey, "Is that you get redundancy in the space that one pump would take up, so you"re going to save space."

Taco Pumps designed their KS vertical split-coupled in-line pumps with an eye toward optimum performance, easy installation and trouble-free maintenance. Like the Armstrong dualArm, the Taco KS split-coupled design facilitates changing the seal without disturbing the motor or piping, making for less downtime. The axial load is hydraulically balanced to increase bearing life, deliver better pump efficiencies, and lower HPHS requirements. KS pumps have a Cinderella-sized footprint and fit easily in tight mechanical rooms, a feature further enhanced with optional support stands that simplify installation and maintenance.

"The beauty of the KS Series is that high horsepower pumps like this can be installed in the ceiling and still allow for ease of maintenance,"says Hettinger, an expert in Taco Pump applications long before he became a Taco Pump distributor in New Jersey. "And because the pump is split-coupled, seals can be changed without having to have to try and disassemble a large pump while on top of a ladder."

Bell & Gossett Pumps" award-winning VSX Series double-suction, split-case, base-mounted, centrifugal pumps feature multiple suction and discharge flange configurations (VCS, VSCS and VSH) "" an innovation that can reduce overall equipment footprint by up to 40 percent. Other industry firsts incorporated in the VSX Series design include hydraulic matching of the pump impeller and casing, a groutless base plate that significantly reduces labor and material costs during installation and "Plug-n-Play" capability allowing simple field modifications for mechanical seals, external seal flushing and wireless monitoring.

"The VSX is just an all-around great product," says Hettinger from Pump ExpressBergen County headquarters where he is the resident expert on Bell & Gossett VSX Series pumps and other Bell & Gossett pump products. "It gives you all the advantages of all Bell & Gossett"s previous vertical split case models with the great added bonus of a reduced footprint."
