Multiquip ST1F Submersible Pump 1/4HP 115V 27GPM

The ST1 Series Submersible Pumps provide a rugged, compact design option when the applications call for value as well as trusted performance. The pumps are an ideal choice for common household moving water applications such as: flooded rooms, flat roofs, fill tanks, basins, fountains and waterfalls. The aluminum pump casing resists corrosion and supports the dissipation of internal heat.

The ST1 and ST1F are designed with powerful capacitor assisted electric motors, internal thermal overload protection, dual shaft seals, and a positive direct drive thermoplastic impeller secured with stainless steel fittings.

All power cords provide strain relief, and the model ST1F is engineered with an internally adapted mechanical float switch to automatically regulate the operation of the pump.

Features:

• Powerful asynchronous 2-pole motor: Equipped with a rugged asynchronous motor designed for long-term service life and maintenance-free operation in residential and commercial dewatering.
  

• 115 VAC 1-phase, 60Hz / 3,450 RPM: Features a high-speed 3,450 RPM motor compatible with standard 115V AC, 1-phase 60Hz electrical outlets for easy, plug-and-play operation.
  

• Corrosion resistant aluminum casing for superior heat dissipation: Constructed with a corrosion-resistant aluminum housing that acts as a high-efficiency heat sink, rapidly dissipating thermal energy to extend the life of the motor.
  

• Lightweight portability, oil-free motor design: Designed for effortless transport, this pump features a highly portable, lightweight frame paired with an eco-friendly oil-free motor that eliminates the risk of water contamination and simplifies maintenance.
  

• Power Cable strain relief: Equipped with an integrated power cable strain relief that protects the electrical connection from tension and pulling, ensuring a secure, long-lasting link even in demanding environments.
  

• Removes water to within 1/4 inch of surface: Engineered for maximum drainage, this pump clears water down to a depth of just 1/4 inch, leaving surfaces nearly dry and ready for final cleanup.
  

• 3/4 inch garden hose adapter included: Equipped for instant deployment, this pump includes a 3/4" garden hose adapter, allowing you to connect standard household hoses for immediate dewatering right out of the box.

• Stainless steel 410 heat-treated shaft: Features a precision-machined 410 stainless steel drive shaft, thermally hardened to optimize structural integrity and ensure long-term rotational stability under heavy loads.
  

• Permanently oil-lubricated triple lip seals for exceptional durability: Features a high-endurance triple lip seal system bathed in a permanent oil reservoir, creating a multi-stage defense against water ingress and ensuring maximum protection for the motor internals.
  

• Rugged reinforced thermoplastic impeller: Equipped with a high-impact, reinforced thermoplastic impeller that is specifically engineered to resist wear and handle small solids without compromising performance.
  

• Removable filter screen for easy cleaning: Equipped with a removable high-flow filter screen designed to intercept solids and prevent impeller damage, facilitating easy routine maintenance and protecting the pump's hydraulic integrity.
  

• 10’ molded power cord: Features a heavy-duty, 10-foot molded power cord designed for maximum moisture resistance and a secure, watertight seal at the motor entry point.
  

• Oil-fee motor with built-in thermal protector: Features an internally protected, oil-free motor equipped with an automatic thermal cutout that prevents overheating, ensuring years of reliable service and total peace of mind during unattended operation.
  

• Industrial integrated mechanical Float Switch (model: ST1F): Equipped with an integrated mechanical float switch for fully automatic dewatering; the pump activates and shuts off autonomously based on water levels, allowing for hands-free operation.
  

• MAX Flow is 27 GPM and MAX Head is 23 ft: Engineered for high-capacity dewatering, the ST1 maintains a 27 GPM maximum output and supports a total dynamic head of up to 23 feet, providing reliable pumping power for residential and commercial applications.
