Monarch BSEF-150TE Electric Motor Driven Self Priming Pump & Repair Parts
Durable Ag-Chemical Transfer: The Monarch BSEF-150TE
The Monarch BSEF-150TE Electric Motor Driven Self Priming Pump is the ideal choice for small to medium-volume agricultural and industrial liquid transfer. Powered by a reliable 1-1/2 HP Totally Enclosed Fan Cooled (TEFC) motor, this pump is engineered to withstand harsh environments where dust, moisture, and chemical exposure are common concerns.
Specifically constructed for the handling of liquid fertilizers (such as nitrogen and phosphorous solutions), the BSEF-150TE offers superior durability compared to standard water pumps. It features a rugged cast iron casing and a high-performance stainless steel mechanical seal with Viton bellows. This seal composition is essential for resisting the corrosive effects of weed control chemicals, ensuring the pump remains leak-free and operational season after season.
Key Features and Benefits
- 1.5 HP TEFC Motor: The Totally Enclosed Fan Cooled motor design prevents external contaminants from entering the motor housing, extending its life in dusty agricultural settings.
- Corrosion-Proof Shaft Design: The semi-open cast iron impeller is “blind hole tapped,” meaning the liquid never comes into contact with the motor shaft, preventing rust and corrosion.
- Chemical Resistant Seals: Equipped with Viton and stainless steel mechanical seals to handle aggressive fluids like fertilizers and herbicides.
- Easy Priming: A large volume casing and a readily accessible priming plug (fitting standard garden hoses) make start-up quick and easy.
- Maintenance Friendly: Designed with a square flange configuration for easy access to internal components during maintenance.
Common Applications
- Liquid Fertilizer Injection: Precision pumping for nitrogen and phosphorous.
- Sprayer Filling: Efficient transfer from nurse tanks to field sprayers.
- General Dewatering: Removal of dirty water from sumps or flooded low spots.
- Lawn Sprinklers: Provides sufficient head pressure for irrigation systems.

Frequently Asked Questions
What type of motor does the BSEF-150TE use?
It uses a 1.5 HP Totally Enclosed Fan Cooled (TEFC) motor, which is designed to prevent dust and moisture intrusion, making it ideal for agricultural use.
Can I pump weed control chemicals with this?
Yes, the pump features a mechanical seal made of stainless steel with Viton bellows. Viton is highly resistant to many agricultural chemicals, including herbicides.
What is the maximum flow rate?
At a total head of 20 feet, the BSEF-150TE is capable of pumping approximately 74 Gallons Per Minute (GPM).
Do I need to check the voltage?
Yes. While the pump is capable of 115/230V, TEFC motors are often pre-wired for a specific voltage. Always check the motor nameplate and your power source before installation.
