Product Description
AF Series Sewage Pumps
AF Series Sewage Pumps provide reliable sewage and wastewater transfer for commercial, industrial, municipal and infrastructure systems across India. Stanflo engineers the range to international design standards and uses durable cast-iron components for demanding submerged operation.
Moreover, the series offers P-type, U-type and E-type impellers for different solids, flow and head requirements. Therefore, users can match the pump to fibrous wastewater, larger solids or higher-efficiency duties.
Reliable Sewage and Wastewater Handling
Wastewater may contain suspended solids, fibrous materials and organic waste. Consequently, standard drainage pumps may clog or lose efficiency.
AF Series Sewage Pumps use non-clog and vortex hydraulic options to maintain dependable flow. In addition, the broad model range covers low-head, high-flow and higher-head duties.
As a result, the AF Series suits wastewater collection pits, treatment facilities, commercial buildings and municipal sewage systems across India.
Key Features and Benefits
The AF Series provides:
- P-type semi-open single-vane impeller
- U-type semi-open vortex impeller
- E-type enclosed-channel impeller
- High-grade cast-iron construction
- Double mechanical seals
- Silicon carbide seal faces
- External oil lip seal
- Auto-cut motor protection
- Epoxy-protected cable entry
- Guide-rail installation option
- Motor ratings up to 20 HP
- Discharge sizes up to 8 inches
- Rated capacities up to 270 m³/h
- Solids passage up to 80 mm
Together, these features support dependable wastewater transfer across a wide range of commercial and industrial applications.
Multiple Impeller Options
The AF Series Sewage Pumps offer three main hydraulic configurations:
P-Type Impeller
The P-type uses a semi-open single-vane impeller for non-clog sewage duties. Therefore, it suits wastewater containing suspended solids and selected fibrous materials.
U-Type Impeller
The U-type uses a semi-open vortex impeller. Consequently, solids have less direct contact with the impeller, which can help reduce clogging in suitable applications.
E-Type Impeller
The E-type uses an enclosed-channel impeller for efficient and clog-resistant operation.
Therefore, users should choose the impeller according to wastewater composition, solids size, required flow and total discharge head.
Durable Cast-Iron Construction
Stanflo uses high-grade cast iron for major pump components, including the casing and motor frame.
Consequently, the pump maintains structural strength during submerged sewage service. Moreover, the compact design simplifies installation inside sewage pits, collection tanks and wastewater chambers.
Mechanical Seal Protection
The pump uses double mechanical seals with abrasion-resistant silicon carbide seal faces.
In addition, an external oil lip seal helps reduce the accumulation of solids around the seal area. As a result, the AF Series Sewage Pumps gain additional protection against water entry and premature seal wear.
However, regular inspection and correct maintenance remain important for dependable long-term operation.
Automatic Motor and Cable Protection
An Auto-cut protector responds when motor temperature rises beyond acceptable limits. Therefore, it helps reduce the risk of overheating damage.
Furthermore, the epoxy-protected cable entry improves waterproof integrity during submerged operation.
Nevertheless, every installation should include suitable electrical controls, overload protection and level management.
Guide-Rail Installation Option
Selected AF Series models support an automatic guide-rail system.
Consequently, technicians can lower, connect or remove the pump from above the pit without entering the sewage chamber. This arrangement can simplify maintenance and improve service access in permanent installations.
AF Series Performance Range
Published range data includes:
- Motor ratings: 0.5 to 20 HP
- Discharge sizes: 2 to 8 inches
- Rated capacities: 9 to 270 m³/h
- Rated heads: 3.5 to 20.5 metres
- Solids passage: 35 to 80 mm
- Maximum submergence depth: 30 metres
- Liquid temperature: 0°C to 40°C
- Electrical options: Single-phase and three-phase on selected models
Therefore, users can choose AF Series Sewage Pumps for compact sewage systems or larger wastewater installations.
However, maximum values do not apply simultaneously to every model. Final selection should follow the exact hydraulic curve and actual system resistance.
AF Series Sewage Pump Applications in India
The AF Series Sewage Pumps may support applications across India such as:
- Sewage treatment plants
- Wastewater treatment facilities
- Sewage and purification tanks
- Septic tanks
- Commercial wastewater pits
- Municipal sewage systems
- Food-processing plants
- Leather and dyeing industries
- Hotels and restaurants
- Schools and public buildings
- Farms and livestock facilities
- Industrial wastewater systems
Moreover, suitable configurations can handle fibrous wastewater when users select the correct impeller and solids passage.
Selecting the Correct AF Series Pump
Correct selection depends on:
- Required flow rate
- Total dynamic head
- Maximum solids diameter
- Fibrous content
- Wastewater composition
- Discharge size
- Electrical supply
- Pit dimensions
- Operating frequency
- Maintenance access
In addition, the installation may require float switches, a control panel, guide rails, non-return valves and isolation valves.
Therefore, engineers should select AF Series Sewage Pumps from model-specific hydraulic and technical data.
