![]() ![]() ![]() Difference between getamped2 us and jp full#At Carver Pump, this means we design the pumps with a full seal chamber/stuffing box that can accommodate a variety of seals or packing.Īlso possible is the use of single or double cartridge seals and nearly any type of seal flush plan. The longer JP means a greater distance between the face of the motor and the hydraulic center of the impeller. The JP shaft extension is the longer of the two pump-specific motor standards. Since the fluid forces acting on the impeller will always place some force or vibration on the impeller, the shorter shaft will not only place a lower torque on a JM shaft but also lead to lower deflection at the seal face, ultimately contributing to better seal life. With a JM shaft extension, the distance from the inboard motor bearing to the seal face is shorter than with a JP shaft. This is because an important contributor to long seal life is limited vibration and radial movement at the seal face. Although the shorter shaft extension allows for fewer seal options, it does have an important advantage: better seal life. JM pumps are more compact, and at Carver Pump, our JM pump back cover also serves as the motor bracket, making for less costly construction. The shorter JM requires the use of a mechanical seal, while the longer JP shaft extension allows for the use of packing. This standard codifies the dimensions of the face where the pump frame attaches, as well as the length and diameter of the shaft where the impeller attaches.įor pump-specific motors, NEMA developed the standard around two different shaft lengths: JM (short) and JP (long). To facilitate industry development of close coupled centrifugal pumps, the National Electrical Manufacturers Association (NEMA) developed a standard for close-coupled motors. In this article, we are focusing on two different varieties of the close-coupled centrifugal pump: those with a JP and those with a JM motor shaft extension. ![]() For some applications, close coupled centrifugal pumps are the clear best choice due to the lower cost and a smaller footprint. By contrast, frame-mounted pumps have their own bearing frame. They use the motor’s bearing and shaft, which makes these pumps more compact and economical.
