Motor Power Rating
The power of a submersible motor must align with the pump's requirements and the depth of water lift. Marwaan offers motors ranging from 0.5 HP to 150 HP to suit every need.
Cooling Mechanism
Marwaan motors come in both water-filled and oil-filled options to match different usage preferences. Oil-filled motors provide enhanced lubrication and insulation, while water-filled motors offer eco-friendly cooling.
Voltage Compatibility
Ensure your motor is compatible with available power supply—single-phase or three-phase—to prevent performance issues or electrical failures. Marwaan motors are built to handle varying voltages efficiently.
Installation Depth
Proper motor sizing and specifications are crucial for deep installations. Marwaan motors are designed to function reliably even at great depths, with robust insulation and sealed construction.
Enclosure and Protection
A motor’s enclosure type (IP rating) and protection features safeguard against water ingress and sand damage. Marwaan submersible motors are sealed and protected for long-term submersion and rough conditions.
Thermal Protection
Overheating can reduce motor lifespan. Our motors are equipped with thermal overload protection to ensure safe operation under varying loads.
Construction Quality
From stainless steel casings to corrosion-resistant windings and dynamic balance, Marwaan motors are built for durability and top-tier performance in all environments.
Key Factors to Consider When Buying a Submersible Motor
Your Complete Guide to Selecting the Perfect Submersible Motor for Every Need
Borewell Size
The pump's outer diameter must be smaller than the borewell's diameter to ensure smooth installation.
Total Head
The head determines how high the water needs to be lifted. Proper calculation of TDH (Total Dynamic Head) is crucial for pump selection.
Delivery Size
This refers to the diameter of the discharge pipe, which must match the size of the storage system.
Discharge Rate
Choose a pump with the appropriate discharge capacity (liters per minute/hour) depending on the area and usage requirements.
Stages
Pumps must be selected based on required head and motor power for optimal performance, referring to efficiency charts.
Cooling System
We offer pumps with water-filled and oil-filled motors to suit different applications and maintenance preferences.
Construction Material
Durability and long-term performance depend on construction — Marwaan Pumps uses high-grade materials like stainless steel shafts, Noryl impellers, and corrosion-resistant motor bodies.
