Vertical, Cantilevered Pump
The design is a cantilever style unit that features non-wetted radial and thrust bearings located above the support plate, with a throttle bushing located immediately above the impeller. The G2C is Carver’s vertical pump for handling fluids at moderate to high flow rates. The standard design is a cantilever style unit.
The G2C is based on the same hydraulics as our vertical sump and horizontal, end-suction pumps. For simplicity, there are only two sizes of bearing frame/motor mounting brackets between the 23 sizes of units. The bearing frame/motor mounting brackets are a one-piece design to insure rigidity and alignment integrity.
As a standard, these units are typically offered in two column depths. The standard column setting has a 12 inch distance between the bottom of the mounting plate and back of the pump casing. The extended column setting is twice this length.
The basic G2C design consists of a pumping (wet) end, column, bearing frame wit integrated motor mounting bracket and top plate. All models feature external impeller adjustment, bearings above the liquid surface, no mechanical seals to maintain, full compatibility with standard NEMA ‘C’ face motors, and some of the most efficient hydraulics in the industry.
Available as an option, discharge piping with Class 150 ANSI flange dimensions can be included (either standard or oversized) on an enlarged support plate should it be a requirement of the installation. Additionally, 316 SS underliners for support plates, suction strainers, inlet tail pipe, external flush lines, and accessories such as automatic greasers and control panels with float switch actuators for automatic start/stop sequencing are also available.
