Little Giant PE-2YSA 115V Submersible Parts Washer Pump
The Little Giant PE-2YSA is a submersible pump designed for parts washers using aqueous solutions or UL-listed solvents with a flash point not lower than 100°F. Its glass-filled polyester plate and nylon volute provide chemical resistance, while a stainless steel motor shaft and Viton shaft seal enhance durability in corrosive environments. The 6-foot cord is plugless, and a Master Builders conduit fitting at the pump housing helps with secure mounting. A removable filter screen simplifies maintenance and debris management, making it suitable for demanding shop settings where reliable solvent handling is required.
Multiquip ST2040T Electric Submersible Trash Pump
The Multiquip ST2040T is a rugged 2″ submersible trash pump with a single-phase motor and 115-volt operation. It’s designed to handle liquids with solids while delivering up to 79 GPM. Its compact footprint and robust construction make it suitable for construction sites, flood recovery, and other environments where large solids and debris are present. This model emphasizes durability and reliable performance in challenging underwater pumping tasks.
Little Giant MDP-1 115V Submersible Stainless Steel Pump
The Little Giant MDP-1 is a 115-volt submersible stainless steel main drain pump designed for heavy-duty pool or water transfer tasks. With a 4260 GPH capacity, this pump excels at removing standing water quickly. It features a 25-foot power cord and sturdy stainless steel construction for resistance to chemical exposure often encountered in pool maintenance and utility drainage. It’s engineered to operate in practical, demanding environments where reliability and corrosion resistance are important.
FOTING Sump Pump 1HP Submersible Water Pump
The FOTING Sump Pump delivers 1 horsepower for efficient drainage, moving up to 4600 GPH with a lift height of up to 31 feet. It’s designed for versatility in wet environments such as pools, ponds, basements, and hot tubs. A 10-foot power cord provides extended reach, and a removable bottom facilitates cleaning and maintenance. The thermoplastic housing adds durability and corrosion resistance, making it suitable for use with a broad range of liquids and debris loads.
RainBro Submersible Sump Pump With 25 Ft Hose
The RainBro submersible sump pump provides a powerful 4000 GPH flow with a 31-foot head height, making it suitable for draining pools, ponds, and basements. It handles 1/3″ solids and includes a 25-foot water hose and 25-foot power cord for extended operation. Its multi-port adaptability includes compatible pipe thread fittings and barbed connectors, enabling direct connections to irrigation or drainage systems. The design emphasizes practicality and ease of use in utility water transfer tasks.
Buying Guide
- Material compatibility: For chemical applications, consider pumps with stainless steel housings, glass-filled plastics, or PPS/PP components to resist solvents and semi-corrosive chemicals. Verify seal and impeller materials for solvent compatibility.
- Submersible vs non-submersible: Submersible pumps save space and reduce priming issues, but for highly aggressive chemicals, non-submersible magnetic drive pumps can offer excellent chemical resistance with inline operation.
- Solvent handling: Ensure the pump is rated for the specific liquids you plan to move, including whether it supports aqueous solutions, emulsions, or UL-listed solvents. Flash point and chemical class influence material selection.
- Flow and head: Match flow rate (GPH) and maximum head (feet) to your application. Higher heads are needed for vertical raise or long discharge runs; higher GPH is useful for rapid water transfer but may require more power.
- Power and cord length: Check voltage compatibility (most listed here run on standard US 115V/120V) and cord lengths to ensure safe, convenient installation in your space.
- Maintenance: Look for removable screens, easily accessible seals, and rotatable pump heads for simpler cleaning and servicing, especially in dirty or debris-prone environments.
- Certifications and safety: For chemical handling, ensure pumps meet appropriate safety standards and are suitable for the intended solvent or solution, with proper seals and materials noted by the manufacturer.
- Installation versatility: Consider pumps with adaptable discharge fittings and hose connections to simplify integration with existing drainage, irrigation, or wastewater systems.
