2 hp Horizontal Centrifugal Pump, Single Stage

High pressure centrifugal pump with horizontal structure, maximum flow 13.5 m³/ h (59.4gpm), maximum head 23m (75ft) and minimum flow 7.3 m³/ h, minimun head 20.5m (67ft). The 3-phase centrifugal water pump has advantages of stable operation, low noise, low failure rate, convenient maintenance, and less land occupation.

Features:

1. The centrifugal pump has the horizontal structure. The diameter of the inlet and outlet are the same. If a protective cover is added, it can be used in the open air.
2. It is easy to install and maintain. No need to dismantle pipeline system, just lifting off the conjunction flat nut of vertical pump. Then all the rotor parts can be taken out.
3. Horizontal centrifugal pump can be operating in series and parallel connection according to the requirements of flow and head.
4. The installation angle of pump outlet can be 0°, 90° and 180° to meet different connection occasions.

Tips: The Influence of the Centrifugal Pump Operating in Low Flow Point.

1. The efficiency is lowered and the power consumption is increased. The centrifugal pump is generally designed to have an efficiency point near the rated condition point. When the centrifugal pump is operated at a low flow operating point, its operating efficiency will drop rapidly. Under normal circumstances, the smaller the flow rate leads to a lower efficiency, so it is very uneconomical to operate in low-flow conditions. In normal conditions, it is necessary to refit the appropriate high-efficiency small pump at this time.
2. The vibration noise increases, which causes environmental pollution and damages the pump components, thus affecting the service life of the pump. At the design operating point, since the flow direction is consistent with the blade direction, the outflow loss, impact loss, and vortex loss are relatively small, approaching zero. However, when the pump is working in a low flow area, the outflow loss, impact loss and vortex loss of the pump over-current component are further increased due to deviation from the design point. These losses are accompanied by a large amount of hydraulic noise and mechanical vibration in the process of being generated.
3. The pump internal backflow increases dramatically, and the inner heat expands, causing the liquid temperature to rise and triggering pump heating, so as to affect the mechanical performance of the pump component. Meanwhile, the performance of pump's cavitation deteriorates, thus further affecting the suction condition of the pump.
4. The radial force of the centrifugal pump increases, thus deteriorating the rotor stress condition of the pump. Since the pump deviates the design working condition point in designing, the liquid flow speed in the volute chamber decreases. However, according to the velocity triangle, the outflow speed of the liquid in the impeller increases on the contrary, so the liquids can not converge and the impact is formed. The radial force will be generated by increasing the pressure constantly.
