GENERAL CATALOGUE
EU REGULATION N. 547/2012
- Pumps with a minimum efficiency index MEI ≥ 40 in conformity with the EU Regulation in force from 1st January 2015.
- The bench mark for the most efficient water pumps is MEI ≥ 70.
- The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with a full diameter The trimming of the impeller adapts the pump to a fixed duty point, resulting in a lower energy consumption. The minimum efficiency index (MEI) is based on the full diameter impeller.
- The functioning of the water pump with variable places of operation can be more efficient and economical if, for example, it is controlled by means of a variable speed motor which adjusts the function of the pump to the System.
GUARANTEE
- All Pumps are generally guaranteed for a minimum of 01 year subject to the terms and conditions of as long as any necessary spare parts fitted during the period of guarantee are original spare parts.

A centrifugal pump is a mechanical device that moves fluid by transferring rotational energy from one or more driven rotors, called impellers, into hydrodynamic energy.
The operation of a centrifugal pump is based on the principle of centrifugal force:
- Suction: A motor rotates the impeller at high speed, creating a low-pressure zone, or partial vacuum, at the center (eye) of the impeller.
- Acceleration: The rotating impeller’s curved vanes catch the fluid and accelerate it tangentially and adially outward, significantly increasing its velocity and kinetic energy.
- Pressure Conversion: This casing is designed with a gradually expanding cross-sectional area, which slows the fluid’s velocity and converts its high kinetic energy into static pressure energy.
- Discharge: The pressurized fluid is forced out through the piping system.
Main Components
The primary components of a centrifugal pump include:
- Impeller: A curved vanes that imparts energy to the fluid.
- Casing: Encloses the impeller.
- Shaft: Transmitting the rotational power.
- Motor/Driver: Provides the mechanical energy to rotate the shaft and impeller.
- Bearings: Support the rotating shaft,
- Sealing System: Prevents the pumped fluid from leaking.

Saling Submersible Pumps
A submersible pump is a type of pump that is designed to be fully immersed in the fluid it is pumping.
Key Characteristics and Working Principle
- Submerged Operation: Operate underwater, often at the source of the fluid.
- “Push” Mechanism: A submersible pump pushes the fluid toward the surface.
- Cooling and Lubrication: Naturally cools the sealed motor and lubricates moving parts,
- Reduced Cavitation: Being submerged also prevents cavitation,
- Quiet Operation: The water surrounding the pump muffles the sound of the motor,
Common Applications

Pump Selection and Operation Guideline
Main Parameters
The information in this section provides the recommendations on selection, installation and operation of the submersible pumps in the most efficient way, avoiding the most typical mistakes and significantly reducing the number of failures.
The water supply system consists of many elements and the main of them are the pumps, pipes, valves, tanks and reservoirs. Each element influences on others.
- Q-H curve to show head vs. capacity relation,
- Q-P curve: power vs. capacity relationship for multistage pumps the curve can be shown for one stage or whole pump,
- Efficiency curve to show stage efficiency with taking into account losses in non-return valve and at the pump inlet
Pump Selection Sequence
- Required capacity and head values,
- Well (borehole) data or ones got by measurement:
- Internal well diameter,
- Static water level,
- Well yield (or output),
- Dynamic water level (pumping water level) to correspond with well yield,
- Well screen/filter depth,
- Chemical composition and solids content of liquid/water,
1st stage. Determining the pump diameter,
2nd stage. Determining the pump capacity,
3rd stage. Determining required pump head,
Static Head of System Characteristic
- Required capacity and head values,
- Well (borehole) data or ones got by measurement:
- Internal well diameter,
- Static water level,
- Well yield (or output),
- Dynamic water level (pumping water level) to correspond with well yield,
- Well screen/filter depth,
- Chemical composition and solids content of liquid/water,
1st stage. Determining the pump diameter,
2nd stage. Determining the pump capacity,
3rd stage. Determining required pump head,
Static Head of System Characteristic
static part is determined by geometric height of water lift relative to dynamic water level and geometric height of the tank.
Dynamic Head of System Characteristic
Dynamic head is determined by losses in the pipeline and takes the form of quadratic dependence: hf (Q) = k·Q2
k – loss coefficient that depends on losses along the pipeline and elements resistances (valves, manifolds, valves, adapters, etc.). That relation is shown as parabola on chart
Pump Installation Requirement
If the required pump capacity is higher than the borehole (well) yield then a dry running sensor shall be applied.
Possible well defects such as
- pipe misalignment,
- poor quality of weld,
- well curvature
may make the pump installation difficult or even impossible. The motor bottom level must be at least 1 m above the well filter. Failure to do so carries the risk of large amount of sand ingress and increased wear of the pump.
Discharge pipe diameter shall be equal to discharge nozzle diameter or differ insignificantly. In selecting discharge pipe diameter the liquid flow-rate shall remain within 1.5 – 3.0 m/s.
1. Pipe selection of lower diameter
Use of pipes of lower diameter than size of discharge nozzle (thread or flanged) for saving purpose results in major loss due to friction and increase of required head.
2. Cable selection of smaller cross-section
Selecting cross-section lower than recommended will lead to significant voltage drop which would affect the motor and cause overheating.
3. Pump capacity exceeds well yield
That leads to dry running operation, which will cause:
- motor overheating
- rapid wear of bearings
- increased corrosion
4. Poor quality of supply voltage and absence of control panels
Direct connection to the power supply does not help to protect the motor from the most typical causes of failure such as current unbalance, phase reversal, under/overvoltage, etc.
5. Built-in non-return valve dismantling
Instrumentation and sensors (water level, pressure, flow rate, voltage, current, number of starts/stops and time of pump operation, etc.) provide valid data on the pump operation and system features for monitoring and timely intervention into pump operation.
6. Absence of instrumentation
Instrumentation and sensors (water level, pressure, flow rate, voltage, current, number of starts/stops and time of pump operation, etc.) provide valid data on the pump operation and system features for monitoring and timely intervention into pump operation.

Saling Submarine Cable
Submarine Cable means Cable of Pump Connection inside Water/Liquid. We sold different submersible or marine cable of m3/RM for single/three phase motors.
Cable Company Name:
- BRB,
- Pedrollo,
- KSB,
- Hatil etc.
A deep tube well marine cable is a specialized, submersible electrical cable designed for powering submersible pumps in deep wells. It must be built to withstand harsh underwater conditions, including pressure, moisture, and chemical exposure. These cables feature robust, waterproof insulation and durable sheathing to ensure safe and reliable operation in demanding environments like deep boreholes for irrigation and water supply.
Key characteristics:
- Durability: Built to withstand the high pressures, abrasion, and temperature fluctuations,
- Waterproofing: Features high-grade, waterproof insulation to prevent water ingress.
- Robust construction: Uses tough materials and sometimes metallic armoring for added mechanical protection.
- Specialized for deep wells: Engineered specifically for continuous immersion in water.
Unlike standard cables, submersible pump cables are engineered to be fully or partially submerged for extended periods. The cable’s construction is crucial for maximizing the pump’s lifespan and efficiency while ensuring safety for those involved in installation and maintenance.
