Reliable Water Pumping for Agriculture, Irrigation and Water Transfer
The Vriha VMB2.0SP5050 is a single-phase centrifugal monoblock pump designed for agricultural irrigation, farm water transfer, domestic water supply, garden irrigation and general-purpose water-pumping applications.
This model features a 2 HP motor, 50 × 50 mm hydraulic size, cast iron pump body, mechanical seal and F Class insulation. It is designed to provide reliable water delivery across suitable operating conditions.
The specified electrical operating range is 170–240 V, making it suitable for installations with a compatible single-phase power supply.
For correct pump selection, the required flow and total head should be considered along with pipe size, pipeline length, fittings, suction conditions and electrical supply.
Technical Specifications
The Vriha VMB2.0SP5050 is a 2 HP single-phase centrifugal monoblock pump. It operates within a specified voltage range of 170–240 V and has a 50 × 50 mm hydraulic size.
The pump body is made of cast iron (CI) and includes a mechanical seal for shaft sealing. The motor is provided with F Class insulation.
The specified duty performance is 240 LPM at 18 m head, while the maximum head is 23 m.
This pump is suitable for water supply, irrigation, water transfer, domestic use, farm applications and garden irrigation, provided that the required system flow and head match the pump's performance.
Hydraulic Performance
The pump's delivered flow changes according to the operating head. At a lower head of 8 m, the approximate flow is 430 LPM.
At 10 m head, the approximate flow is 390 LPM, while at 12 m head, it is approximately 350 LPM.
The pump can deliver approximately 315 LPM at 14 m head and 280 LPM at 16 m head.
The stated duty point is 240 LPM at 18 m head. At higher heads, the approximate flow reduces to 180 LPM at 20 m head and 90 LPM at 22 m head.
The specified maximum head is 23 m.
Actual installation performance may vary depending on pipeline length, pipe diameter, bends, valves, fittings, suction conditions and total system resistance.
50 × 50 mm Hydraulic Design
The 50 × 50 mm designation identifies the specified hydraulic size of the pump.
Pump sizing should always be considered together with the complete piping system. Pipe diameter, pipeline length and fittings create friction losses that can affect the final operating point.
For this reason, the pump should be selected according to the complete hydraulic requirement rather than motor horsepower alone.
Cast Iron Pump Construction
The pump casing is made of cast iron (CI), providing a strong and durable enclosure for the hydraulic assembly.
Cast iron construction is commonly used in water-pumping equipment where mechanical strength and reliable casing performance are required.
The suitability of the pump should also be considered in relation to the water quality and operating environment.
Mechanical Seal
The pump is equipped with a mechanical seal for shaft sealing.
The mechanical seal helps control leakage around the rotating shaft between the hydraulic and motor sections. Proper installation, alignment and operating conditions are important for maintaining sealing performance.
F Class Insulation
The motor is specified with F Class insulation.
Insulation class indicates the thermal classification of the motor insulation system. Motor service life also depends on operating temperature, electrical supply, loading, ventilation and correct installation.
Electrical Supply
The VMB2.0SP5050 is designed for single-phase operation within a specified voltage range of 170–240 V.
Before installation, confirm that the available supply at the pump location is compatible with this range. Electrical protection and wiring should be selected according to the motor's electrical requirements and applicable installation practices.
Operating the pump outside the specified electrical conditions may affect motor performance and service life.
Where Can It Be Used?
The hydraulic characteristics of this model make it suitable for several general water-pumping duties when the required operating point falls within its performance range.
Agricultural Irrigation
The pump can be used for transferring water through suitable agricultural irrigation systems where the required flow and head match the available performance.
Farm Water Transfer
It can be used to move water between storage tanks, reservoirs and distribution points on farms and agricultural properties.
Domestic Water Supply
The pump may be suitable for household or building water-transfer applications when the system requirement is compatible with its flow and head performance.
Garden Irrigation
It can be used for garden, landscape and small irrigation systems requiring a suitable combination of flow and head.
General Water Transfer
The pump can be used for transferring suitable water between tanks and other locations through a properly designed pipeline system.
Understanding the Duty Point
The 18 m duty head and 240 LPM flow represent the specified operating point for this model.
A customer requiring approximately 240 LPM at 18 m total head can use this information as a starting point for pump selection.
However, the complete system must be evaluated because the actual operating point depends on the interaction between the pump and the pipeline system.
How to Select the Correct Pump
Before purchasing, determine the required flow in LPM or m³/h and the total dynamic head in metres.
Also consider the vertical lifting height, pipeline length, pipe diameter, number of bends, fittings, valve losses and water-source conditions.
The available voltage and electrical phase should be checked before installation. Once these values are known, compare the system requirement with the manufacturer's performance data.
Why Horsepower Alone Is Not Enough
Two pumps with the same motor power can have different hydraulic performance.
Impeller design, pump geometry, rotational speed and hydraulic characteristics determine how much water a particular model can deliver at a given head.
The correct selection method is:
Required Flow + Required Head + Electrical Supply + Application → Suitable Pump
Selecting a pump based only on horsepower may result in insufficient flow, excessive energy use or unsuitable system performance.
Vriha Centrifugal Monoblock Pump Range
Vriha offers centrifugal monoblock pump models in different capacities and electrical configurations.
Customers can compare models according to motor power, phase, voltage, hydraulic size, head, flow, construction and application.
Each model should be evaluated using its own technical specifications and performance data.
