What is the Hemisphere?
Hemisphere is a versatile and portable water monitor designed for firefighting applications that require high-flow water delivery in hard-to-reach areas. Unlike traditional portable monitors, Hemisphere does not rely on gravity for stability. Hemisphere has an abundance of mounting options, enabling it to be mounted on various surfaces and structures. This monitor can flow up to 500 GPM (2000 LPM) and offers unmatched flexibility, allowing fire crews to direct water streams exactly where they need them, even in confined or elevated spaces.

Key Features of the Hemisphere Portable Monitor

Quick-Attach Mounting System
The Hemisphere monitor’s quick-attach mounting system secures it to various surfaces with ease, offering a reliable hold and rapid setup in emergencies. The release knob ensures fast detachment when needed. However, for safety purposes, a pressurized chamber ensures the monitor stays secure when water is flowing.

Flow Rate
The Hemisphere monitor offers a flow capacity of up to 500 GPM (2000 LPM), providing sufficient water flow for most firefighting scenarios. Its integrated stream straightener ensures that water is delivered with maximum reach and minimal turbulence, helping to control fires quickly and efficiently.

Full Hemisphere of Coverage
Hemisphere’s unique design allows for full 360-degree rotation of the main waterway when not flowing water, along with an 80-degree pivoting water stream. This enables firefighters to direct water flow in virtually any direction without repositioning the monitor. We refer to this as a “full hemisphere” of coverage.

Rotation Lock Release Levers
The Hemisphere monitor features rotation lock release levers on both sides, enabling 45-degree incremental rotation when not flowing. A pressurized chamber ensures the lock stays secure under flow, preventing unintended movement. Pulling the levers back toward the inlet releases the pin for smooth rotation, while automatic locking re-engages when the levers are released.

Patented Articulating Waterway
The Hemisphere monitor features a double ball pivot with a synchronizing mechanism, ensuring smooth, precise movement. Built with the same patented articulating waterway as the Flex™ and BlitzFire® monitors, it delivers proven performance on the fireground. The articulating knuckles allow for quick and effortless stream angle adjustments to adapt to any situation.

Double Ball Swivel & Lock Knob
Each pivot offers 40 degrees of rotation, providing a total sweep of 80 degrees. When unlocked, the double ball pivot moves freely for easy positioning. The lock knob allows you to adjust resistance as needed or tighten fully to hold the monitor in a fixed position.

Locking Bail-Type Handle
The Hemisphere’s locking bail-type handle ensures secure water flow control. The handle locks in place to prevent accidental discharge, providing precise control for starting and stopping water as needed. To operate, simply pull the handle lock knob before opening or closing the valve.

Half-Ball Valve
The half-ball valve design ensures a high flow rate while minimizing friction loss, delivering efficient performance under demanding conditions.

Dual Crank Handles
The Hemisphere’s dual crank handles provide precise control of the water stream from any mounting position, ensuring adaptability no matter where the monitor is deployed.

Built-In Carry Handle
The Hemisphere features a built-in carry handle, making it easy to transport and quickly position for deployment.
Hemisphere Mounting Options
The portable Hemisphere monitor offers unparalleled versatility with its secure mounting options. It can be attached to fixed mounts or a durable backbone that clamps to stationary objects, with each backbone supporting a single monitor. Featuring up to 42 pin positions, the Hemisphere mounting backbone allows precise placement for optimal performance.
Constructed from hard-coat anodized aluminum and stainless steel, the clamps are built for durability and flexibility, enabling quick, tool-free attachment to various surfaces, including I-beams, tank lips, industrial scaffolding, and round or irregular shapes. With standard 2-inch hitch compatibility, the system ensures reliable deployment in challenging or unconventional locations, delivering critical water coverage where it’s needed most.

Cross-Pin Mount
The cross-pin mount can be mounted in 42 different bin positions on the Hemisphere mounting backbone.

Mounting Block
The mounting block can be installed from the back or in locations where the back side of the mounting surface is inaccessible.

I-Beam Clamp
Ideal for attaching to I-beams and other structural surfaces.

Flex Clamp
Attaches to round objects between 3” and 24” (76 mm to 601 mm) in diameter, such as bollards or pipes, expanding the monitor’s mounting capabilities.

Hitch Receiver Mount
The 2″ (65mm) backbone is sized to fit into any standard 2″ x 2″ (65mm) Class III or Class IV hitch receiver.

Tank Lip Clamp
The tank lip clamp is intended for use on floating roof tanks that are constructed in accordance with the API 650 2007 standard, with top angle stiffening rings between 2-1/2” x 2-1/2” x 1/4” to 4” x 4” x 1/2”.

Parallel Bar Clamp
Designed for handrails, particularly useful in staircases and confined areas. The parallel bar clamp is intended for use on a pair of round parallel bars between 1.5” and 2.0” diameter, spaced between 5” to 29” apart, on center.
