Little Giant Water Systems Product Catalog

Inline Pressure Solutions

Little Giant offers a range of inline pressure solutions designed to increase and maintain water pressure in various applications. These systems are compact, easy to install, and feature built-in protections against common failure modes.

Inline CP

The Inline CP is a packaged system that increases pressure by up to 60 psi and handles up to 35 gpm. It features a small, compact design, NEMA 4 electronics enclosure, and can be mounted in any configuration. It is powered by a 1.5 hp motor and includes surge protection, voltage underload protection, locked pump protection, open circuit protection, short circuit protection, and overheated controller protection. It is capable of operating with more than one pump in parallel for larger volume demand applications.

Inline 400

The Inline 400 is designed for city water pressure boosting, pressurizing water from cistern tanks, re-pressurizing after filtration, and irrigation system boosting. It utilizes a proven Franklin Electric pump and motor for reliability. It features simple flow-based controls, a protective cap for outdoor use, whisper-quiet operation, and can be installed vertically or horizontally. It has a 1/3 hp motor and a maximum water temperature rating of 120°F/49°C.

Inline Controls

Franklin Electric's Inline Controls include five pump starting and control devices that pair with submersible or surface pumps up to 20 amps (approximately 3 hp). These controls provide or boost system water pressure, often without the need for an additional bladder tank. They offer various system protections, including dry run, dead head pumping, over amperage, locked system, and over-pressurization. Features include a daily motor rotation start to prevent system locking and an automatic restart feature.

• SWC (Smart Flow Control): Flow activated smart pump start control, designed for use in conjunction with a pump where starting and stopping the system based on water usage is desired. Activates with a flow of 0.25 gpm or greater. Includes built-in check valve and protects against dry run, overcurrent, and dead-head conditions.
• ADJ (Adjustable Low-Pressure Backup): Similar to SWC but allows for adjustable low-pressure cut-in points (22, 29, or 36 psi).
• CTL (Control with Pressure Regulation): Features a built-in pressure reducing valve to allow customization of maximum output pressure.

Jet Pump and Tank Systems

Little Giant offers factory-assembled jet pump and pre-charged pressure tank systems for supplying fresh water to rural homes, farms, and cabins. These systems are designed for installations where the vertical distance from the pump to the pumping water level does not exceed 25 feet.

Shallow Well Jet Pump & Tank System

This system includes a cast iron pump casing, a dual voltage (115/230V) motor, and a pressure switch preset at 30/50 psi. It features a 1-1/4" Suction/Intake and a 3/4" Discharge on the tank. The impeller and diffuser are made of glass-filled thermoplastic. The system includes a pressure gauge and a 14 U.S. gallon (53 litre) pre-charged steel pressure tank with a high-performance Butyl Rubber diaphragm.

Shallow Well Jet Pumps

Designed for fresh water supply to rural homes, farms, and cabins, these pumps are suitable for installations where the vertical distance to the pumping water level does not exceed 25 feet. They feature a cast iron casing, dual voltage motors, and a pressure switch preset at 30/50 psi. The suction is 1-1/4" and the discharge is 1" NPT. Models include a pressure gauge, stainless steel motor shaft, and precision-engineered thermoplastic impeller, diffuser, nozzle, and venturi.

Convertible Jet Pumps

These pumps are suitable for installations where the vertical distance to the pumping water level does not exceed 90 feet. They feature a cast iron casing, dual voltage motors, and a pressure switch preset at 30/50 psi. The suction is 1-1/4" and the discharge is 1" NPT. A brass flow control valve and pressure gauge are included. An injector kit is provided for both shallow and deep well installations.

Lawn Sprinkler Pumps

Little Giant offers LSP Series pumps for residential and commercial lawn and turf sprinkler systems, irrigation, gardens, and general water transfer. These pumps are self-priming and feature cast iron casings for durability.

LSP Series

The LSP Series pumps are designed for lawn and turf sprinkler systems. They feature a cast iron casing, single-phase capacitor start, 115/230 dual voltage motors (on 1 hp and 1-1/2 hp models), and higher than standard NEMA service factors. The pumps have a 2" NPT suction and a 1-1/2" NPT discharge. They are fully serviceable with a two-year warranty.

End Suction Pumps

Little Giant's LGDR Series end suction pumps are suitable for water circulation, booster service, spraying systems, jockey pump service, and general purpose pumping. They feature a back pull-out design for easy access to internal parts.

LGDR Series

These pumps are designed for various applications including water circulation and booster service. They feature a robust cast iron volute, enclosed impeller design for increased efficiencies, and are suitable for horizontal or vertical installation. The pumps come with ODP standard NEMA motors and are factory wet tested.

Pressure Tanks

Little Giant RL Series pressure tanks are designed for maintaining water pressure in residential water pump systems when the pump is not running. They feature heavy-duty 20-gauge steel construction and a 304 Stainless Steel water connection with leak-safe technology.

RL Series

The RL Series tanks are available in inline, horizontal, and vertical configurations. They feature a high-performance variable geometry Butyl Rubber diaphragm membrane and an internal polypropylene liner. All tanks are NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 approved for safe, clean drinking water. They can be installed in series or in parallel for increased system capacity.

4" Submersible Well Pumps

Little Giant offers a range of 4" submersible well pumps designed for new installs and replacement applications. These pumps are suitable for wells, cisterns, ponds, lakes, and streams, and are designed for use in 4" and greater diameter water well applications.

Submersible Well Pumps

These pumps offer five performance ranges: 5, 8, 12, 16, and 22 gpm, with horsepower ranging from 1/2 to 1.5. They are NSF/ANSI 61 Certified for drinking water safe materials. All stainless steel components are 300 series grade or better. The pumps feature a 1.25" NPT discharge pipe connection, an integrated internal check valve, and are 100% factory performance tested.
