Submersible Effluent Pumps (GNS)

Key features of Submersible Effluent Pumps:

• Handles water containing suspended particles up to 35 mm sphere.
• Vortex impeller designed to avoid clogging.
• Motor: 2800 rpm, oil-filled, "F" class insulated, works with single- and three-phase power.
• Jacketed motor with coolant filling – allows prolonged dry running.
• Two ball bearings running in an oil bath for reliability.
• Dual mechanical seals for enhanced durability.
• Standard cable: 5 m length, 1.5 sq. mm, 4 core, double encased submersible cable (extra length available on request).
• All-cast iron body with stainless steel jacket.
• Stainless steel hardware for easy maintenance.
• Horizontal discharge with 50mm female flange.

Advantages of Submersible Effluent Pumps:

• Efficiently handles gray water and wastewater with small solids, reducing clogging risks.
• Installed underwater, eliminating the need for a separate pump house.
• Reduced noise and vibration as it operates below liquid level.
• High durability with corrosion-resistant materials and sealed motor housing.
• Direct submersion ensures better motor cooling and reduced energy loss.
• Sealed design minimizes exposure to contaminants and lowers maintenance needs.
• Automatic operation with float switches or level sensors.
• No cavitation risk due to submerged design.
• Suitable for septic systems, residential wastewater, treatment plants, and industrial effluent.

Types of Submersible Effluent Pumps:

Based on Impeller Type:

• Vortex Impeller Pumps: Allow solids to pass without direct contact; ideal for suspended solids.
• Grinder Pumps: Equipped with cutting blades for fibrous/solid waste, creating fine slurry.
• Channel Impeller Pumps: Handle high water volumes with smaller solids, commonly used in sewage treatment.

Based on Application:

• Residential Effluent Pumps: Compact, lightweight, ideal for septic systems and basement drainage.
• Commercial Effluent Pumps: Medium-duty for hotels, hospitals, and buildings with higher flow needs.
• Industrial Effluent Pumps: Heavy-duty, continuous operation for slurry, chemicals, and wastewater.
• Agricultural Effluent Pumps: Used in irrigation drainage, livestock wastewater, or slurry pits.

Based on Discharge Capacity:

• Low Head Pumps: For short-distance effluent lifting and drainage.
• High Head Pumps: Suitable for long-distance or higher elevation pumping.

Based on Material of Construction:

• Cast Iron Submersible Effluent Pumps: Strong and durable, commonly used for sewage and municipal applications.
• Stainless Steel Submersible Pumps: Corrosion-resistant, suitable for chemical effluents and aggressive liquids.
• Plastic-Body Pumps: Lightweight and affordable, usually for residential/light-duty applications.
