The Hydrus is Reinke's lightest weight irrigation system that gives you big results. Recommended for small or irregularly shaped fields (including grain, forage, sod, vegetable, game and hobby farms), it's lightweight structure and flotation tires offer reduced rutting and easy towing (ability to tow is standard). The system also offers savings through reduced operating costs due to fewer maintenance needs and smaller energy requirements.
The system uses four-inch mainline pipe throughout. Today's low-pressure water sprinklers are 90-95 percent efficient, reducing the required gallons per minute (gpm) per acre by as much as 20 percent. This improved efficiency has allowed us to redesign the structural hardware to better fit the requirements for small acreage fields and low gpm applications.
The Hydrus comes with six or nine foot ground clearance under the span trussing to meet the requirements of most crop and field conditions.

The nine-foot ground clearance system features a wider wheelbase for added stability.
The system is lightweight and easy to install and maintain, with only five different structural parts in an entire span assembly to deal with. With minimal annual maintenance, the system will provide years of dependable service.

The Hydrus by Reinke Micro Pivot was conceived and designed for small and medium size fields. The result was a small, lightweight machine powered by DC voltage, eliminating the need for 480 volt, three phase power. Here are some reasons why the Hydrus by Reinke is the right choice for your small acreage:

• The Right Choice for your energy source with options that include 1) 110 or 220 volt single phase commercial electrical power or 2) small engine powered generator.
• The Right Choice for low operating and maintenance costs.
• The Right Choice for durability, with all major components galvanized.
• The Right Choice for a simple and easy-to-operate system
• The Right  Choice for multiple field locations (ability to tow is standard)
• The Right Choice for easy installation, as little or no concrete is required at the pivot center.
• The Right Choice for reliability, with the full support of Reinke Mfg. Co., Inc.

The Hydrus by Reinke Micro Pivot center-drive gear motor is powered by a high efficiency 1/8 HP, 48 volt DC motor. When coupled with the 257:1 gear ratio, this gear motor provides extremely high torque output and fast rotation speeds. A five-tower (637 ft) Hydrus by Reinke Micro Pivot can complete a full revolution in just over 14.5 hours.

The Hydrus by Reinke Micro Pivot final-drive is designed with a beveled gear for maximum efficiency. The 6:1 gear ratio can be towed without the need for a special disconnect hub.

The system structure is galvanized for lasting aesthetics, durability and long life. Under normal operating conditions galvanized protection will give many years of service.

• Commonality of parts for easy installation and maintenance.
• Minimum span arch results in uniform ground clearance for today's efficient sprinkler packages.
• Allows for spans (distance between support towers) in a variety of lengths at 10-foot increments.
• Provides a pivot point that can be easily towed from location to location.

The Hydrus by Reinke Micro Pivot uses four-inch galvanized steel pipe throughout. All pipe sections are identical in 10-foot lengths with sprinkler outlets positioned every five feet.
Pipe flanges are 1/4" steel fastened together with six bolts. Flanges are machined to permit the use of O-ring gaskets (pioneered by Reinke in 1968) for a perfect seal.

The Hydrus by Reinke Micro Pivot meets both UL and CUL requirements for safe operation. The Master Control Panel is engineered using the highest quality components and it is easy to understand. Standard control features include:

• Easy-to-understand operating instructions
• Incoming power disconnect
• DC control voltage
• Forward and reverse selection
• Variable speed control
• Low-pressure shut-down
• Wet or dry operating selection
• Alignment safety shut-down protection

• Span lengths available in 10 ft. increments up to 131.5 ft.
• End booms are available in 12, 20 and 30 ft. lengths.
• Pipe throughout is 10 ft. x 4" OD.
• Ground clearance is six feet with a nine foot option available
• Galvanized for long term durability.
• Flanges are six-hole and sealed by using an O-ring gasket for long life.
• Wheel base on a six-foot clearance system is 10.5 feet and on a nine-foot clearance option is 14.5 feet.
• Hook and receiver span attachments (pioneered in 1968 by Reinke) provide maximum flexibility.
• Pivot column uses a triple-lip gasketed coupler together with an oversized 10" outer bearing.
• Concrete pivot pad may not be necessary due to the unique pivot design.
• Sprinkler outlets are located every five feet for uniform water application.
• Sprinkler options available in various models of high-efficiency products.
• Rigid or hose combination sprinkler drops are available in various lengths.
• Automatic drain is located at each tower.
• Operates on slopes up to 10%.
• Multiple power options include 110 or 220 volt single phase commercial electrical power or small engine powered generator.
• Ability to tow is a standard feature.

The Hydrus by Reinke Micro Pivot can be ordered or later modified to have these extra features:

• Automatic Reverse - End Tower: to provide exacting system reverse or shut down at a predetermined location.
• Automatic Reverse - Pivot Column: to permit adjustable system reverse or shut down from a convenient location.
• End Gun Control: controls an end gun by turning it off and on at predetermined locations.
• Electric Valve Control: permits the operator to turn a mainline valve off and on from the control panel, and can be installed to shut the valve off should the system shut down unexpectedly.
• Fertilizer Pump Control: permits the operator to turn a fertilizer pump off and on from the control panel, and turns the pump off when the system shuts off (external receptacle required).
• Pivot Operating Light: conveniently mounted on the main control panel, for a vivid nighttime indicator that the system is on and running.
• Other Options: contact your Hydrus by Reinke dealer for other system options, such as air relief valve, choice of sprinklers and drops, valves that may enhance or provide safety for your system's operation, or main line pipe tie-in.
