**Efficient, Compact, and Reliable Water Transfer Solution**
## Introduction
The SCM Self-Priming Centrifugal Pump is a high-performance pump designed for domestic and light industrial water supply systems. It features a robust build, high efficiency, and the ability to automatically prime itself after the first filling, making it the ideal choice for users requiring a dependable and easy-to-install water pumping solution.
Whether you're sourcing water from wells, tanks, or underground reservoirs, the SCM pump ensures uninterrupted water flow with excellent suction lift and pressure stability. Its high-grade components and compact design allow for versatile installation and long service life.
## Product Features and Benefits
### ✅ **Self-Priming Functionality**
Unlike standard centrifugal pumps, SCM models can automatically prime themselves after initial water filling. This makes them perfect for installations where suction lift is required, such as drawing water from below ground level.
### ✅ **High-Performance Copper Motor**
Equipped with 100% copper winding motor and built-in thermal overload protection. Ensures stable operation even under high-temperature or overcurrent conditions.
### ✅ **Durable Housing Materials**
Constructed from cast iron or stainless steel, with anti-corrosion internal components, the SCM pump is resistant to wear and rust in both clean and slightly contaminated water.
### ✅ **Low Noise & Energy Efficient**
Engineered for quiet operation and optimized for energy-saving. Ideal for residential applications where noise reduction is important.
### ✅ **Compact & Lightweight Design**
Easy to install in tight spaces. Can be mounted on walls, floors, or mobile platforms, with low maintenance requirements.
### ✅ **Thermal & Overload Protection**
The integrated motor protection system prevents overheating and extends service life, especially in unstable voltage environments.

SCM-550 | 0.55kW / 0.75HP | 45 | 35 | 8 | 220V | 1"x1" | Cast Iron |
SCM-750 | 0.75kW / 1HP | 60 | 42 | 9 | 220V | 1"x1" | Cast Iron |
SCM-1100 | 1.1kW / 1.5HP | 70 | 48 | 9 | 220V | 1"x1" | Stainless Steel |
SCM-1500 | 1.5kW / 2HP | 80 | 55 | 9 | 220V | 220V/380V | Stainless Steel |
> Custom voltage (110V/60Hz, 380V/50Hz) and flange sizes available on request.
## ⚙️ Working Principle
The SCM self-priming centrifugal pump works by creating a vacuum inside the pump chamber, allowing atmospheric pressure to push water into the inlet pipe. Once primed, the impeller rotates at high speed, converting mechanical energy into kinetic energy, and delivering a strong, continuous flow.
The self-priming function is made possible by a built-in air-water separation system that expels air and maintains water within the pump body after shut-off — so restarting doesn’t require re-priming.
## Applications
This pump is suitable for a wide variety of uses, including:
### Domestic Use
* Water supply from tanks, underground storage, or shallow wells
* Boosting household water pressure for showers, taps, and appliances
* Garden irrigation and sprinkler systems
### Agriculture & Farming
* Drip irrigation or spray irrigation in small farms
* Water transfer from reservoirs to fields
* Livestock watering systems
### Commercial & Industrial Use
* Car washing stations
* Water circulation for HVAC cooling
* Pressure boosting in restaurants or guesthouses
### System Integration
* Works well with water filters, controllers, and pressure tanks
* Can be used in solar water systems or off-grid installations
## Competitive Advantages
* **Compared to jet pumps**: SCM pumps have higher flow rates and more energy-efficient operation
* **Compared to submersible pumps**: Easier maintenance and no need to be submerged in water
* **Compared to diaphragm pumps**: More suitable for clean water and less pulsation during output
* **Price-to-performance ratio**: Excellent value for light-duty to moderate applications
## Packaging & Installation
* Each unit includes: pump, user manual, warranty card, fittings (on request)
* Standard carton box or wooden case for international shipping
* Installation can be done horizontally, near water source; priming is needed only once
* Suitable for both fixed or mobile installations
## ❓ Frequently Asked Questions (FAQ)
**Q1: Can the SCM pump handle dirty water?**
A: It is primarily designed for clean or slightly dirty water. Avoid pumping water with solid particles or sand.
**Q2: Do I need to fill it with water before the first use?**
A: Yes, initial priming is required once. After that, the pump can automatically reprime itself.
**Q3: How long can this pump run continuously?**
A: SCM pumps are rated for intermittent duty. For continuous operation, allow cooling periods or integrate with a thermal controller.
**Q4: Does it come with a pressure switch or tank?**
A: No, but it can be connected to both. We offer matched pressure tanks and switches as accessories.
