Patterson V.I.P. series of vertical in-line centrifugal pumps offer a simple, an economical and an efficient alternative to end suction and horizontal split case pumps in flows less than 1,500 GPM.
Patterson V.I.P. series of vertical in-line centrifugal pumps are easily and inexpensively installed, since they require no foundation or concrete pad. Only standard piping supports on either side of the pump are needed. Vertical in-line suction and discharge flanges are on a common center line, 180 degrees apart, for easy installation into an existing pipe line.
Patterson V.I.P. series of vertical in-line centrifugal pumps are available with either packing or a mechanical seal. When packing is utilized , a two-piece gland is provided for easy removal and packing installation. The mechanically sealed pump can be converted to packing in the field.
Competing in-line pumps offer mechanical seals on standard models, but do not provide a gland, and the mechanical seal is installed underneath the volute cover. This does not afford the user the flexibility of converting to packing if the mechanical seal fails. Nor, does the design allow for inspection of the mechanical seal without "tearing down" the pump.
Patterson V.I.P. series of vertical in-line centrifugal pumps standard JP/JM motor format, designed for this service by NEMA and Hydraulic Institute, provides quality integral drive systems that assure the uniformity of tolerances, minimum shaft deflection and bearings properly sized for the job.
