Monarch BSEF-300TE Electric Motor Driven Self Priming Pump & Repair Parts
Efficient Ag-Chemical Transfer: The Monarch BSEF-300TE
The Monarch BSEF-300TE Electric Motor Driven Self Priming Pump is a versatile and durable solution for handling liquid agricultural chemicals and general water transfer. Powered by a 3 HP Totally Enclosed Fan Cooled (TEFC) motor, this pump is engineered to perform reliably in environments where dust, moisture, and weather are factors.
Designed with the needs of the agricultural industry in mind, the BSEF-300TE is excellent for pumping liquid fertilizers, including nitrogen and phosphorous solutions. It features a rugged cast iron construction and a specialized mechanical seal made of stainless steel and Viton bellows. This seal composition ensures that the pump can safely handle weed control chemicals and other aggressive fluids without premature failure.
Key Features and Benefits
- Reliable 3 HP TEFC Motor: The Totally Enclosed Fan Cooled motor protects internal components from dirt and moisture, ensuring long operational life (Standard 230V, Single Phase).
- Corrosion-Resistant Impeller: The semi-open cast iron impeller features a blind-hole tapped design. This prevents the liquid from coming into contact with the motor shaft, effectively eliminating shaft corrosion.
- Chemical Compatibility: Equipped with a Viton and stainless steel mechanical seal, specifically chosen for its resistance to harsh agricultural chemicals and fertilizers.
- Self-Priming Efficiency: A large casing chamber allows for rapid priming. The unit includes a priming plug designed to fit a standard garden hose for easy filling.
- Versatile Applications: With 2-inch NPT suction and discharge ports, this pump balances high pressure with substantial flow volume, making it ideal for spraying and dewatering.
Common Applications
- Liquid Fertilizer Pumping: Efficiently moves nitrogen and phosphorous solutions.
- Herbicide & Pesticide Transfer: Viton seals provide necessary chemical resistance.
- Lawn & Sprinkler Systems: High pressure output supports irrigation networks.
- General Dewatering: Capable of pumping dirty water from sumps or trenches.
