FOam Equipment 

The Otter™ pump is the world's first ultra-lightweight fully composite submersible pump used for remote water sourcing and flood control operations. The Power Unit can be mounted on a standard pick up truck with a 6.5’ bed and a 3200lb payload. Using the latest advancements in composite body technology, the Otter™ (Patent pending) weighs in at only 85 lbs (38.5 kg), while still being able to produce flows up to 2000 GPM (7570 LPM). Being physically manageable by one or two firefighting personnel is a unique deployment advantage, greatly simplifying loading and general use.

Due to its unique lightweight design, the main power unit can remain at an easily accessible location (i.e. street level) while the pump is carried/lowered to the remote water source (subway tunnels, flood channels, etc.) up to 100 feet away (depending on the hydraulic umbilical length). The discharge connection on the Otter™ uses a standard 5” Storz adapter, which can be further adapted to multiple lines to reduce pressure loss for the pump.

Features and Benefits of the otter Pump

The otter pump has immense benefits being the first and only composite source pump

  • The world's first composite, compact, ultra-lightweight, high-volume floating submersible source pump

  • Portable "floating hydrant"™ providing reliable positive pressure water supply to fire pumper apparatus

  • Superior corrosion-proof and corrosion-resistant properties in both fresh and salt water

  • No priming or drafting required

  • Increases availability and accessibility of more open water sources. May allow opportunity for improved water supply credit for insurance rating

  • Physically manageable by one or two emergency personnel for ease of deployment and retrieval

  • Deployment flexibility over a wide variety of terrain and infrastructure configurations

  • May improve water shuttle operations by eliminating a drafting engine and providing faster tanker/tender fill times

  • Easily refueled while operating during long-term operations

  • Power unit enclosure skid can remain at an easily accessible location remote from water supply, up to 100 ft

  • Can be operated in environmentally sensitive areas. Uses non-toxic, biodegradable hydraulic fluid

Perfect for the most dire fire fighting situations

The Otter System is capable of getting to water sources that a normal fire fighting apparatus cannot. It enhances the ability to access more open water sources previously deemed unattainable for fire fighting purposes.
