GH

Available as either a frame mounted (GHF) or close coupled (GHC) unit, the GH is based on the same product platform as our vertical pumps and shares many of the same parts with them.

For added simplicity, the entire series is covered by only three bearing frames and can be had in whole pump or modular kit form. The GHC is fully compatible with standard, off-the shelf NEMA JP frame motors, and all models feature a back pull-out design, removable suction covers, and casings rotatable in 90° increments for different field piping orientations.

Other common features for the GH include 316 SS shaft sleeves, keyed impellers to prevent accidental spin off, dynamic balancing to ISO G2.5 guidelines, and regreasable bearings secured with locking rings as standard. These features combine to produce shaft deflection values so low that they actually exceed the requirements of ANSI B73.1M-1991 and overall, provide some of the most efficient hydraulics in the industry.

Common options for the GH include replaceable wear rings, cartridge seals, and flush plans. Along with these, higher alloy material options such as Ni-Al-Br and CD4MCuN and a full range of motor and baseplate choices are also available.
