Frequently Asked Questions?

Customers can contact Vriha Pump with their application and pumping requirements for assistance with product specifications, pump selection, technical information, availability and quotation requirements.

For proper pump selection, provide the required water flow, total head or lifting height, pipe size, water source, delivery distance, electrical supply and application. This information helps identify a suitable Vriha pump model.

No. Pump discharge depends on the complete hydraulic design, impeller, speed, head, efficiency and system resistance. A pump should be selected according to the required flow and head rather than HP alone.

Pump flow rate is the quantity of water delivered by a pump over a specific period. It is commonly expressed in litres per minute (LPM), litres per second (L/s) or cubic metres per hour (m³/h).

Pump head represents the energy or pressure that a pump can provide to move water through a system and is generally expressed in metres. Total system head can include static lifting height and losses caused by pipes, fittings and other components.

Yes. Vriha manufactures fire-fighting pump solutions for applications requiring water flow and pressure for fire-protection systems. The pump should be selected according to the requirements of the complete fire-protection system.

Yes. Vriha offers dewatering pump solutions for construction sites, pits, basements, industrial areas and other applications where unwanted water needs to be removed.

Selected Vriha pump models can be suitable for continuous-duty applications when operated within their specified electrical, hydraulic and installation conditions. The operating requirements of the particular model should always be followed.

Yes. Suitable Vriha pumps can be used for industrial water transfer, circulation, machine cooling and other water-handling applications. Pump selection should consider flow, head, water temperature and operating conditions.

Yes. Vriha manufactures openwell submersible pump solutions for applications involving open wells, tanks, reservoirs and other suitable water sources.

Yes. Vriha manufactures borewell submersible pump solutions for suitable borewell water pumping applications. Selection depends on borewell diameter, water level, required flow, total head and electrical supply.

Vriha centrifugal pumps can be used for agricultural irrigation, domestic water supply, water transfer, industrial water circulation, machine cooling and other suitable clean-water applications according to the model's operating specifications.

Vriha offers selected pump models designed for specified voltage ranges. Voltage range varies according to the individual model. Customers should check the technical specification of the selected pump before installation.

Yes. Vriha manufactures three-phase pump models for agricultural, industrial and commercial water-pumping applications.

Yes. Vriha manufactures selected single-phase pump models for agricultural, domestic and other applications where single-phase electrical supply is available.

A centrifugal pump is normally installed outside the water source and draws or receives water through the suction system. A submersible pump is designed to operate while submerged in the water. The suitable pump depends on the water source, installation and pumping requirements

A centrifugal monoblock pump combines the electric motor and centrifugal pump in a single compact unit. These pumps are commonly used for agriculture, irrigation, domestic water supply, water transfer and industrial water circulation.

The pump should be selected according to required flow rate, total head, pipe diameter, water source, delivery distance, lifting height, operating conditions and electrical supply. Vriha technical specifications and performance curves should be considered before selecting a model.

Vriha offers centrifugal, monoblock, openwell and borewell submersible pump solutions for agricultural irrigation. The correct model depends on required water flow, total head, water source, pipe size, lifting height and available electrical supply.

Vriha manufactures centrifugal pumps, monoblock pumps, single-phase pumps, three-phase pumps, openwell submersible pumps, borewell submersible pumps, dewatering pumps, mixed-flow pumps and fire-fighting pumps for different water pumping requirements.

Vriha Pump is an Indian pump manufacturer offering water pumping solutions for agriculture, irrigation, domestic water supply, industrial applications, construction dewatering and fire-fighting systems. Vriha product ranges include centrifugal monoblock pumps, openwell submersible pumps, borewell submersible pumps, dewatering pumps, mixed-flow pumps and fire-fighting pumps.

he required pipe size depends on the specific pump model and application. Using the recommended suction and delivery pipe size helps maintain proper pump performance and reduces unnecessary friction losses.

There is no single discharge value for a pump at all conditions. Water discharge changes according to the pumping head, pipeline arrangement and operating point. Refer to the Vriha performance chart for the expected discharge at the required head

Maximum head depends on the particular 2 HP model and pump design. The correct maximum head should be taken from the technical specification or performance curve of the selected model.

Yes, the pump can be used for suitable agricultural irrigation applications when the required flow, head, pipeline size and water source are within the pump's operating range.

Do not select a pump based only on HP. Check the required water discharge, total head, suction conditions, pipeline length and diameter, water source and electrical supply. The pump performance curve should match your actual operating requirement.

Before installation, check the electrical supply, correct cable and protection, suction and delivery pipeline, pipe joints, water source and installation position. The pump should be installed according to the manufacturer's recommended installation procedure.

Appropriate electrical protection should be provided according to the motor configuration and electrical supply. Protection against overload, short circuit and unsuitable voltage conditions helps protect the motor and pump.

Low discharge can be caused by excessive pumping head, undersized or blocked pipes, air leakage on the suction side, incorrect installation, low voltage, water-level conditions or operating the pump outside its recommended range.

Provide the required water discharge, total head, water-source type, pipe size, installation details and available electrical supply to the Vriha Pump team. These details help identify the appropriate pump model.
