A 15 HP submersible sewage pump is a heavy-duty wastewater pump designed to move large volumes of liquid containing solids, sludge, and debris without clogging. MASTRA's 15 HP sewage submersible pump combines a non-clog impeller, cast iron or stainless steel construction, and a sealed submersible motor to deliver reliable, continuous performance in the most demanding municipal and industrial environments.
Whether your application involves raw sewage transfer, industrial effluent, sludge dewatering, or stormwater drainage, this pump is engineered to keep operations running without interruption.

A 15 HP sewage submersible pump is a fully sealed, motor-driven pump that operates while submerged in the fluid it is moving. At 15 horsepower (approximately 11 kW), it sits in the mid-to-high power range for wastewater applications—capable of handling high flow rates and significant head pressure while passing solid particles that would block conventional centrifugal pumps.
MASTRA's 15 HP submersible sewage pump is purpose-built for liquids that standard pumps cannot handle: raw sewage, mixed sludge, oil-contaminated wastewater, brine, and slurries. The non-clog design ensures solids pass freely through the pump body, reducing downtime and maintenance costs.
The pump uses a single-channel or vortex non-clog impeller that allows solid particles—typically up to 50–80 mm in diameter—to pass through without becoming lodged. This is the defining feature for sewage and sludge applications, where fibrous materials, suspended solids, and debris are always present.
Cast iron body: Cost-effective and durable for standard municipal sewage and wastewater applications
Stainless steel (304 or 316L): Recommended for corrosive media including saltwater, acidic effluent, brine, and food-processing wastewater
Cast iron is better suited for high-volume municipal applications where abrasion resistance is the priority. Stainless steel is the better choice when chemical corrosion or hygiene requirements are a concern.
The 15 HP (11 kW) motor is hermetically sealed, oil-filled, and designed for continuous submersed operation. Key motor specifications typically include:
Power: 15 HP / 11 kW
Voltage options: 380V / 415V / 460V (50Hz or 60Hz configurations available)
Insulation class: F or H
Protection rating: IP68
Double mechanical seals—typically silicon carbide on silicon carbide—protect the motor chamber from fluid ingress. This seal arrangement is rated for abrasive, fibrous, and corrosive liquids, extending operational life in harsh sewage environments.
MASTRA's 15 HP sewage submersible pump is engineered to handle:
Raw municipal sewage and wastewater
Industrial effluent and process water
Sludge and slurry (with moderate solid content)
Oily wastewater and mixed liquids
Saltwater and brine (stainless steel variant)
Stormwater and drainage water with debris
MASTRA pumps are manufactured in compliance with international standards, including CE certification, ensuring the product meets European safety, health, and environmental requirements. MASTRA's parent company, Guangdong Ruirong Pump Industry Co., Ltd., holds 100+ honors and certificates and exports to 120+ countries, reflecting a manufacturing standard trusted globally.

15 HP submersible sewage pumps are a core component in municipal lift stations and wastewater treatment plants. They transfer raw influent between treatment stages and manage stormwater overflow during peak events.
Factories, food processing plants, slaughterhouses, paper mills, and chemical facilities generate high volumes of contaminated water. The non-clog design ensures solids and fibrous materials don't halt production.
Sludge dewatering operations require pumps that can handle thick, high-solid-content mixtures. A 15 HP sludge dewatering pump with a vortex impeller maintains flow even when solids concentrations are elevated.
Groundwater and slurry removal on construction sites demands portable, robust submersible pumps capable of handling sand, gravel, and sediment without seizing.
Mine drainage water is often abrasive and may carry fine particulate matter. A cast iron 15 HP submersible pump provides the durability needed for continuous operation in these environments.
MASTRA (Guangdong Ruirong Pump Industry Co., Ltd.) is a Guangdong-recognized Innovative Enterprise and Famous Export Enterprise with over 33 years of production experience and a monthly output exceeding 80,000 units.

Q: What size solids can a 15 HP non-clog submersible sewage pump handle?
A non-clog submersible sewage pump at 15 HP typically handles solid particles up to 50–80 mm in diameter, depending on impeller design. Vortex impellers offer the highest solid-passage capacity, as the liquid and solids travel through the pump casing without direct contact with the impeller blades.
Q: What is the difference between a vortex impeller and a single-channel impeller in sewage pumps?
A vortex impeller creates a rotating flow pattern that moves solids through the casing without blade contact, making it ideal for stringy or fibrous materials. A single-channel impeller offers higher hydraulic efficiency and is better suited for applications where solids are present but not dominant. For raw sewage with rags and fibrous waste, a vortex design is generally preferred.
Q: Can a 15 HP submersible sewage pump handle oil-contaminated or saline wastewater?
Yes, provided the correct material is specified. Stainless steel 316L construction with Viton seals is recommended for oily, saline, or mildly corrosive liquids. Standard cast iron models are better suited for clean-to-moderately-contaminated municipal sewage where chemical resistance is not critical.
Q: Is a 15 HP sewage submersible pump available in both 50Hz and 60Hz configurations?
Yes. MASTRA manufactures sewage submersible pumps in both 50Hz and 60Hz variants to suit different regional power supply standards. Voltage can also be customized to match local grid requirements.
Q: How do I select the right 15 HP submersible pump for my wastewater application?
Selection depends on four key parameters: required flow rate (m³/h), total dynamic head (m), solid particle size, and liquid type. MASTRA's Pump Selection Tool can help match these parameters to the right model. For complex applications, contacting MASTRA's technical team directly is recommended.
MASTRA's engineering team is available to assist with pump selection, custom configurations, and OEM sourcing for 15 HP sewage submersible pumps.
