Thrust balancing is a necessary part in every centrifugal pump arrangement. Thrust forces are magnified in high pressure, multi-stage pumps to a level that should be eliminated or at least reduced. . Table 1 shows that the MCTF calculations considered both balancing line return locations (suction drum/suction nozzle) with and without an .

Seldom used as a primary thrust bearing in centrifugal pumps. For high speed centrifugal pumps. This bearing can run at higher speeds than the 7200PDU and 7300PDU series and requires less thrust load to maintain proper traction forces between the ball and raceway surfaces.

Waterous CM/CMU Series Pump has been the best-selling two-stage fire pump for decades. But we've made it even better. Waterous engineers were tasked with updating the pump with features it shares with our best-selling single-stage fire pump. In this article, we will delve into the dual-stage centrifugal fire pump, its advantages over single-stage pumps, and the key features of the Waterous CM/CMU Series Pump.
When choosing a configuration, the first decision must be based on the need for a single-stage pump or a two-stage pump. Unlike positive displacement pumps, centrifugal
Two-Stage Centrifugal Pump Diagram
Before we dive into the specifics of the Waterous CM/CMU Series Pump, let's first understand the basic concept of a two-stage centrifugal pump. A two-stage centrifugal pump consists of two impellers mounted on a single shaft within the same pump casing. The first impeller, known as the "low-pressure" impeller, increases the pressure of the water before it enters the second impeller, known as the "high-pressure" impeller. This dual-stage design allows for higher pressure and flow rates compared to single-stage pumps.
Single Stage Pump vs. Two-Stage Pump
The main difference between a single-stage pump and a two-stage pump lies in the number of impellers and the resulting pressure capabilities. A single-stage pump has only one impeller, which limits its ability to generate high pressures. On the other hand, a two-stage pump, like the Waterous CM/CMU Series Pump, utilizes two impellers to increase the pressure in two stages, resulting in higher pressure output.
Single Stage vs. Multistage Pump
While a single-stage pump is suitable for applications where moderate pressure is required, a multistage pump is designed for high-pressure applications. A multistage pump consists of multiple impellers stacked in series within the same pump casing, allowing for even higher pressure outputs compared to a two-stage pump. However, for many firefighting scenarios, a two-stage pump like the Waterous CM/CMU Series Pump strikes the right balance between pressure and efficiency.
Centrifugal Fire Pump Diagram
A centrifugal fire pump operates on the principle of centrifugal force to move water through the pump and into the fire suppression system. The pump's impeller spins at high speeds, creating a centrifugal force that pushes the water outward, increasing its pressure. In the case of a dual-stage centrifugal fire pump, the water passes through two stages of impellers, each increasing the pressure before exiting the pump.
Multiple Stage Centrifugal Pumps
Multiple-stage centrifugal pumps, such as the Waterous CM/CMU Series Pump, are designed to handle high-pressure applications where a single-stage pump may not be sufficient. By utilizing multiple impellers in series, these pumps can deliver the necessary pressure for firefighting operations, making them essential equipment for fire departments and industrial facilities.
