The Honeycomb Screens are rigid, strong, made of heat-treated hard anodized aluminum and come in a variety of sizes.  The screens are streamlined in one direction only and when mounted at the duct exits, with blunt side outwards, they permit easy inflow and restricted outflow.  Thus the velocity of the exit jet is greater than in the duct, which is as it should be.

The 1002 Series Electric Propulsion Systems provide the ultimate in reliability and efficiency. The Electric Motor efficiency is over 90%. The 1002 Electric Thruster produces a high level of thrust in the forward direction and 90+% in reverse operation. The venturi shape of the 1002 Thruster is ideally suited for Electric Drive because the Prop Turns Faster for the Same Power. Streamlined Brushless DC, oil filled and pressure balanced direct drive electric submersible motors.  Capable of going to full ocean depth. Customized Solutions/Systems for R & D Programs or Prototype Vehicles, small or large. These electric thrusters can be precision matched to each application. Independently Tested Ready-to-Purchase. The 1002 series electric thrusters are offered with a matching integrated or stand-alone controller option, oil filled and pressure balanced, eliminating the need for a motor controller housed in a separate one atmosphere bottle.

PROVEN DEPENDABILITY: Reference Operating Point With the 4200 Motor: 600 lbsf, 3,000 psi, 10 gpm (37.9 l/min). Reference Operating Point With the 4900 Motor: 200 lbsf, 3,000 psi, 1.97 gpm (7.46 l/min). Much Faster Response Time, Propeller only 9.27″ dia. of Anodized Heat Treated Aluminum Alloy. Much Lower Torque Reaction on the Vehicle ( Low Displacement Motors ). THE MOTOR IS COVERED BY A STREAMLINED FAIRING TO REDUCE FLOW BLOCKAGE AND DRAG. The Motor Requires No Separate Adapter Shaft, Bearings, Compensation Chamber, etc. Heavy Duty Construction, All Metal, No Plastic. Higher Jet Velocity Means Greater Speed Capability. Automatic Tilting Screen For No Thrust Loss (optional). Light Weight: Dry Weight with Motor ( 33 lbs. ). Wet Weight with Motor ( 22 lbs. ) 90%+ Reverse Thrust. Much Higher Efficiency

THE 1002HL HONEYCOMB HYDRAULIC THRUSTER WITH A STREAMLINED MOTOR. Reduced Cavitation, Optimized for Both Shallow and Deep Running. Honeycomb Screens* of Hydrodynamic Design Protect Divers, Marine Life and the Prop. Honeycomb Screens** Which Cancel  80% Of The Prop Torque While Reclaiming Thrust By Reducing Jet Whirl. Custom Propellers with Ultra High Thrust To Torque Ratio. Propellers Have Lenticular Blade Sections with No Camber for Symmetrical Ahead – Astern Operation. The 4200SA Hydraulic Motor Has a Stainless Steel Casing and Shaft. The Motor has Retrofittable Silicon-Carbide Shaft Face Seals With Indefinite Life in Sand. The Seals Can’t Be Blown Out by Case Pressure Surges.
