Monarch BSEF-500TE Electric Motor Driven Self Priming Pump & Repair Parts
Reliable Liquid Fertilizer Transfer: The Monarch BSEF-500TE
The Monarch BSEF-500TE Electric Motor Driven Self Priming Pump is a robust industrial pump engineered for the rigorous demands of agricultural chemical transfer and general dewatering. Powered by a 5 HP Totally Enclosed Fan Cooled (TEFC) motor, this unit provides the durability required to operate in dusty or damp environments without compromising performance.
Designed specifically for handling liquid fertilizers, including nitrogen and phosphorous solutions, the BSEF-500TE features a premium construction profile. The pump casing is cast from rugged iron, housing a large chamber that facilitates rapid self-priming. Critical to its longevity is the stainless steel and Viton mechanical seal, which offers superior resistance to weed control chemicals and aggressive fluids that would degrade standard seals.
Key Features and Benefits
- Heavy-Duty 5 HP Motor: Comes equipped with a reliable TEFC motor (1 Phase, 230V standard) designed to prevent overheating and contaminant ingress.
- Corrosion Protection: The semi-open cast iron impeller is “blind hole tapped,” a design feature that prevents liquid from contacting the motor shaft, thereby eliminating thread corrosion.
- Chemical Resistant Seals: Utilizes a mechanical seal made of stainless steel with Viton bellows, ensuring compatibility with agriculture chemicals and fertilizers.
- Maintenance Friendly: Includes a replaceable stainless steel sleeve (BSEF-500 and BSEF-750 models) to protect the motor shaft and simplify seal replacement.
- High-Volume Flow: Features 3-inch NPT suction and discharge ports to handle significant fluid volumes efficiently.
- Easy Priming: A dedicated priming plug fits standard garden hoses for quick filling of the large casing chamber.
Common Applications
- Liquid Fertilizer Transfer: Safe movement of nitrogen and phosphorous solutions.
- Weed Control: Compatible with common agricultural herbicides and pesticides.
- General Dewatering: Effective for removing dirty water from sumps or flooded areas.
- Irrigation: High-head capabilities suitable for sprinkler and lawn systems.

Frequently Asked Questions
What is the primary use for the BSEF-500TE pump?
The BSEF-500TE is designed for transferring liquid agricultural chemicals, specifically nitrogen and phosphorous solutions, as well as dewatering dirty water. Its materials are selected to resist corrosion from these fluids.
What voltage does the BSEF-500TE require?
The standard BSEF-500TE (Order No. 616889) is equipped with a single-phase, 230V motor. Please verify your specific site voltage before installation.
Does the impeller handle solids?
The pump features a semi-open cast iron impeller designed to handle dirty water and light solids found in agricultural applications, but it is not a trash pump designed for large debris.
What makes this pump resistant to corrosion?
It utilizes a stainless steel and Viton mechanical seal, a blind-hole tapped impeller (protecting the shaft from liquid contact), and a replaceable stainless steel shaft sleeve.
