General Data

Application

The MSV, MSVC and MSVN series of centrifugal pumps are multifunctional products designed to convey various fluids ranging from tap water to industrial liquids at different temperatures, flow rates and pressures. The MSV Series is designed for non-corrosive fluids, while the MSVC(304SS) and MSVN(316) are suitable for slightly corrosive liquids. Listed below is a sampling of applications:.

Water Supply Systems: Water filtration and transfer, and pressure boosting in high-rise buildings. Industrial Booster Systems: Process flow systems, cleaning systems, high-pressure washing systems,and fire fighting applications. Industrial Liquid Transfer Systems: HVAC systems, boiler water supply, condensing system, car wash systems, and alkalis. Water Treatment Systems : Ultrafiltration systems, reverse osmosis systems, distillation systems, separators, swimming pools. Irrigation Agricultural: Farmland irrigation, spray irrigation, dripping irrigation.

Operational Parameters

Thin, clean, non-flammable and non-explosive liquids containing no solid granules and fibers. Liquid temperature:

Normal temperature type: +70°C, +158°F Hot water type: +70°C… +120°C, 158°F…+248°F

Ambient temperature: up to 40°C, 104°F Altitude: up to 1000m, 3280 ft.

Pumps MSV, MSVC and MSVN Series are vertical non-self priming multistage centrifugal pumps, coupled to a TEFC IP55 electric motor. The motor output shaft directly connects with the pump shaft through a coupling. The cylinder and flow passage components are assembled between the inlet and outlead heads using industrial grade connecting rods. The inlet and outlet are located at the pump bottom in the same plane , and designed for inline piping connections. The pump can be equipped to prevent dry-running conditions, phase loss, over and under voltage, over-current, plugged coditions,and outfitted with other sensory devices designed to protect the pump and process.

General Data

Minimum Inlet Pressure NPSH

In the event that the pressure in the pump is lower than the steam pressure used to convey liquid, cavitation will occur. To avoid cavitation, a minimum pressure at the inlet side of the pump shall be guaranteed. The maximum suction head can be calculated with following formula:

H = Pb x 10.2 - NPSH - Hf - Hv - Hs

Pb= atmospheric pressure [bar] (can be set as 1bar)In a closed system, Pb means system pressure [bar]NPSH= Net positive suction head [m], It can be read out from the point of possible max. flow rate shown on NPSH curve Hf = Pipe and fitting friction loss at the inlet [m]Hv= Static pressure [m]Hs= Safety margin Minimum 0.5m delivery head

If the calculated result H is positive, the pump may run under the max. suction H. In case the calculated result H is negative, a minimum delivery head at the inlet pressure is necessary.

Parallel Operation

Connecting several pumps in parallel will increase the system output more than a single large pump.

- Applicable to different working states necessary in a variable flow system.

- Increasing the possibility of water supply when the pump is in failure. Because in case of pump failure, only part of the system flow is effected.

Multiple pumps can be connected in parallel to increase system capacity demands.

General Data

2. Performance curve tolerances conform with ISO.

3. Measurement is with 20 °C air-free water, kinematic viscosity of 1mm2 /sec.

4. Operation of the pump must be within the performance region shown by the heavier line on the performance curve to prevent overheating caused by insufficient flow or motor overloading caused by excessive flow rates.

Performance Curves

1. All the performance curves are based on the measured values of a motor at a constant speed of 3500 rpm.

Stage

First number: Stage x 10

Second number: Number of small impeller

Model and frequency of pump

Pump Q-H curve

The heavier dark line represents the recommended performance region

Eta Curve

Represents the efficency of the pump. For pumps with small impeller, it’s efficency will be 2% lower than shown by the curve

Power Curve

Represents the input power of each stage, which is divided into integrate impeller type (1/1) and the type with small impeller (2/3).

NPSH Curve

Expresses the average value of all curves of this series. A safety margin of 0.5m shall be taken into consideration when making a selection.

Stage - presenting integrate impeller type (1/1) and the type equipped with small impeller (2/3)
