TECNADYNE 220 User Manual
MODEL 220
DC BRUSHLESS HYDRAULIC PUMP
Due to its extremely small size, light weight and reasonable
cost, the Model 220 DC brushless hydraulic pump is ideally
suited for small manipulators, tool packages, pan & tilts and
a variety of other subsea applications.The Model 220s reliability
has been proven over many years service in the worlds harshest
offshore environments.
The fixed displacement gear pump of the Model 220 is available
with four pump displacements delivering flows of 1.9 liters /
minute, 3.4 liters / minute, 4.3 liters / minute and 5.8 liters / minute. The extremely reliable DC brushless
motor is available at various voltages ranging from 95vdc to 330vdc. And because the DC brushless motor
has variable speed control, the pump speed and flow can be continuously varied to meet the hydraulic
demand, thus conserving considerable electrical power when compared to variable displacement pumps
which operate at fixed speed.
The Model 220 pump will deliver rated flow at pressures to 21mPa. The investment cast aluminum casing
of the pump is protected from the ocean environment with a rugged ceramic epoxy coating. The motor
housing is hard anodized aluminum.
For depths to 1,500 meters, the power and control electronics can be housed within the hard anodized
aluminum motor casing, greatly simplifying the installation and electrical interface. For full ocean depth
rating, the electronics are installed in a remote, one atmosphere housing (either the customers housing
or one supplied by Tecnadyne) and the motor housing and electrical cabling are oil filled for pressure
tolerance.
The Model 220 is available for operation at voltages from 95vdc to 330vdc (150vdc standard) supplied
by a well filtered batery bank, rectified and filtered AC or a DC power supply. Pump speed is controlled
with a 0-5v analog speed control signal. Alternately, the motor can be wired so that it operates at full speed
only when the main power is applied, which reduces the control and connector complexity in some
installations. Also, a full servo RS232 or RS485 input controller is available but this must be installed in
a remote, one atmosphere housing. Please refer to the Tecnadyne website for detailed installation and
interface instructions.
The standard depth rating of the Model 220 DC brushless hydraulic pump is 1,500 meters - full ocean
depth is an available option. Alternate operating voltages and pump flow rates, hydraulic fittings, customer
specified subsea connectors and cables, stainless steel or titanium housings and custom mountings are
also available.
