VERIWIS 26 GPM / 138 ft Head

Engineered for demanding applications, this VERIWIS septic pump delivers 26 GPM with a 138 ft head. It uses a robust 1/2 HP motor and a multi-stage impeller system to maintain consistent pressure for water transfer tasks. A capacitor start ensures smooth operation, while stainless steel construction and a sealed motor protection system guard against water ingress. Its versatile design supports installation in steel, concrete, or earth wells, making it well-suited for septic maintenance, irrigation, fountain circulation, livestock watering, and pond management.

Key features include: a robust stainless steel valve body and filter screen, maintenance-free operation, and a design that handles tough environments. This makes it a practical option for cisterns requiring reliable submersible pumping with solid head capacity.

VERIWIS 32 GPM / 207 ft Head

This VERIWIS unit delivers 32 GPM with a formidable 207 ft head, powered by a 1 HP motor and a multi-stage impeller. It employs a premium stainless steel construction for corrosion resistance and a fully sealed motor protection system to prevent water ingress, supporting long service life in challenging environments. The pump is designed for diverse water management needs, including septic maintenance, irrigation, fountain circulation, and livestock watering, and it is compatible with steel, concrete, or earth wells.

Highlights include: reliable capacitor-start for smooth starts, durable stainless steel components, and an adaptable installation profile that suits various cistern and well setups. This model is built to handle higher lift requirements while maintaining steady performance.

WASSERMANN 32 GPM / 207 ft

WASSERMANN’s 32 GPM, 207 ft bottom-suction pump is built for heavy-duty cistern and deep-well applications. It features a stainless steel body, built-in capacitor start, and a hermetically sealed motor with thermal protection for longer life. The unit’s filtration mesh helps reduce debris-related issues, and the design is suitable for 4-inch wells and larger casings. This pump excels in septic tank setups and other demanding water-transfer tasks where sustained head is essential.

Key considerations include: compatibility with larger well casings, protection against overheating, and the practicality of adding filtration to prevent sediment buildup in challenging water sources.

Little Giant 35 GPM / 39 PSI

Little Giant’s submersible cistern pump delivers about 35 GPM with a pressure rating around 39 PSI, powered by a 1/2 HP motor. Constructed from stainless steel with a robust thermoplastic discharge head, it resists corrosion and impact. It includes a built-in flow control and a 20-foot power cord with a 3-prong plug. An inlet filter helps protect the pump from debris when submerged, though the unit is not self-priming and should be positioned below water level. This makes it a practical option for small to medium cistern systems requiring reliable water transfer and straightforward installation.

WASSERMANN 32 GPM / 174 ft

This WASSERMANN 4-inch submersible pump is rated for 115V/60Hz at 3/4 HP, delivering up to 32 GPM with a maximum head of 174 ft. It features a stainless steel body, built-in capacitor start, and a hermetically sealed motor to prevent overheating. The design supports use in 4-inch well casings and larger, offering solid performance for cisterns that demand dependable lift and flow. The product emphasizes ease of use and long-term reliability in septic tank and aquifer applications, with emphasis on robust construction and thermal protection.

Buying Guide

• Head and flow needs: Match the pump’s maximum head (ft) to the vertical lift required by your cistern or deep-well setup, and ensure the GPM rate suits your demand without overworking the motor.
• Voltage and motor power: Most residential cistern pumps operate at 115V or 230V. Choose a motor size (1/2 HP, 3/4 HP, 1 HP, etc.) that aligns with your lift requirements and energy efficiency goals.
• Build quality: A stainless steel body and corrosion-resistant components extend service life in damp, mineral-rich environments. Look for sealed motors and robust impellers designed for continuous duty.
• Bottom suction vs. standard discharge: Bottom-suction designs are advantageous when sediment is present at the well bottom, reducing clogging. Ensure the outlet size (commonly 1-1/4″ FNPT) matches your piping.
• Filtration and debris handling: Some models include filtration meshes or screens to reduce debris intake. Consider adding a debris barrier or pre-filter if your water source has sediment.
• Installation considerations: Check well diameter compatibility (4″ wells and larger in many models). Some pumps require submersion below water level and proper priming practices to prevent airlocks.
• Maintenance and warranty: A long warranty and accessible replacement parts are important for peace of mind. Keep the motor protected from overheating and ensure cooling during operation.
• Energy efficiency: Higher head pumps often consume more power; balance performance needs with long-term operating costs when selecting a model.
• Safety: Ensure proper electrical grounding, use GFCI protection as needed, and follow local codes for well and cistern installations.
