Waterous Pump Packing Kit CMH / CSH

Packing repair kit for replacement of high pressure stage packing in CMH and CSH Series Pumps.
Kit includes six (6) Braided Graphite Packing Rings.

The Waterous Pump Packing Kit CMH / CSH Series Pumps is a type of mechanical seal that is used to prevent water from leaking out of the pump shaft and bearings. The pump packing is located around the pump shaft and is compressed against the shaft by a gland or packing nut.

Waterous CMH and CSH Series Pumps are high-pressure centrifugal fire pumps that are designed for use in municipal fire departments and industrial firefighting applications. The pump packing for these pumps is made up of a series of packing rings, which are typically made from materials such as graphite or PTFE. These rings are arranged in a stack, with each ring overlapping the one below it. The rings are then compressed against the pump shaft by the gland or packing nut, creating a seal.

When the pump is in operation, water is drawn into the pump and pressurized, creating a hydraulic force that can push water past the pump packing and out of the pump. To prevent this from happening, the pump packing is designed to create a tight seal around the pump shaft, which prevents water from leaking out.

As water flows past the pump packing, some of it is absorbed by the packing material, which swells and creates a tighter seal around the pump shaft. Over time, however, the packing material may become worn or compressed, which can lead to leaks. When this occurs, the packing must be replaced with a new set of rings.

The pump packing for Waterous CMH and CSH Series Pumps is an essential component of these high-pressure centrifugal fire pumps, and is designed to prevent water from leaking out of the pump shaft and bearings. By ensuring that the pump packing is properly installed and maintained, users can help to extend the life of their pump and ensure that it operates safely and efficiently.
