Description
LEO ECH & ECHm Series Horizontal Multistage Stainless Steel Pumps (Models ECHm4-40, ECH4-50, ECHm4-60, & ECH4-60)
When your application demands high water pressure but cannot tolerate the loud operational noise of standard jet or peripheral pumps, the LEO ECH/ECHm Horizontal Multistage series is the professional’s top choice. A highly refined engineering solution in the Afrogulf catalog, these pumps feature a multi-chambered hydraulic end. Instead of relying on a single massive impeller, the multistage design passes water through a series of smaller stainless steel impellers. This step-by-step pressure boosting allows the pump to generate phenomenal manometric head while operating with incredibly smooth, whisper-quiet efficiency—making it perfect for indoor residential installations.
Beyond their quiet performance, the entire wet-end of the ECH series—including the cylindrical casing, impellers, and drive shaft—is forged from premium AISI 304 stainless steel. This makes them highly resistant to corrosion and perfectly suited for handling high-temperature liquids (up to 85°C) and slightly aggressive water. Driven by a heavy-duty copper-wound motor and utilizing high-quality mechanical seals, these pumps provide leak-free, continuous-duty performance. Whether you are running a high-end residential shower system, an industrial washing station, or a commercial water filtration setup, the ECH series guarantees clean, high-pressure delivery.
Key Features & Specifications:
-
Whisper-Quiet Multistage Design: Utilizes multiple internal impellers to multiply water pressure smoothly, drastically reducing operational noise and vibration compared to standard pumps.
-
AISI 304 Stainless Steel Hydraulics: The pump body, impellers, and drive shaft are entirely constructed from premium stainless steel to completely prevent internal rust and protect water hygiene.
-
High-Temperature & RO Capable: The robust mechanical seals and stainless construction allow the pump to safely handle hot liquids (up to 85°C) and purified RO water.
-
Continuous Duty Copper Motor: Equipped with a highly efficient, thermally protected copper motor designed to run continuously without overheating during heavy demand.
-
Space-Saving Horizontal Profile: The compact, inline cylindrical design allows for easy installation in tight pump rooms, under counters, or within specialized water treatment skids.
Applications: Highly recommended for residential indoor pressure boosting, commercial reverse osmosis (RO) and water treatment systems, industrial washing equipment, HVAC circulation, and food & beverage processing. (Note: Designed for clean water and chemically non-aggressive liquids).
