System Description
The Katadyn PowerSurvivor 80E watermaker system has several components. Refer to the
System Diagram (Figure A-1) in the Appendix for an overview of the components of the system
and their interconnections.
Motor/Drive/Pump & Membrane Housing: At the heart of the watermaker system
is a high-pressure, positive-displacement pump. The pump is powered by a reliable 12 (or 24)
VDC electric motor. An oil-bath gearbox (drive assembly) converts the rotary motion of the
electric motor to a powerful, reciprocating, linear motion for driving the pump piston. The pump
pressurizes input seawater to approximately 800 psi (pounds per square inch) and forces
product freshwater through a semipermeable membrane located in the membrane housing. The
motor, gearbox and pump have been integrated into a single, compact piece of equipment—
with low power consumption, quiet operation and a small footprint. The membrane assembly is
a separate unit which allows it to be mounted in a convenient location.
Prefilter Assembly: The prefilter assembly consists of one prefilter housing and a
standard 30-micron prefilter element constructed of polyester fibers. Two standard elements
ship with each system. In some exceptional circumstances, an optional second prefilter
assembly with a 5-micron prefilter element may be needed (see Kits & Accessories). The
prefilter assembly is separate unit which allows it to be installed in a convenient and accessible
location.
Valves: Two high-quality plastic 3-way valves are supplied. The prefilter 3-way valve selects
between (1) seawater input for normal operation and (2) an alternate intake line for inputting
membrane preservative or a cleaning solution. The product 3-way valve allows easy routing of
product water to either (1) a freshwater collection tank for normal operation or (2) a drain
location for discarding during initial startup, testing, preservation or cleaning operations.
Hoses and Hardware: Each PowerSurvivor 80E watermaker is shipped with appropriate
hoses and hardware sufficient to perform a normal installation. This includes two high-pressure
hoses (3’ and 5’) for carrying pressurized seawater from the pump to the membrane housing
and reject brine water from the membrane housing back to the pump. The 1/2" I.D. reinforced
plastic hose is used for seawater intake and reject brine. The smaller, 1/4" I.D. clear plastic
hose is for routing product freshwater. There are also hose clamps and mounting bracket
hardware for the prefilter assembly and membrane housing, and a TDS (Total Dissolved Solids)
meter for testing and monitoring the quality of product freshwater.
Customer-supplied Equipment: Every installation represents a unique challenge!
You or your installer will need to provide:
1. a reliable source of clean seawater for input to the prefilter 3-way valve
2. plumbing to an appropriate drain location for the reject brine water
3. a plumbing solution for your freshwater collection tank
Our Promise: Every Katadyn PowerSurvivor 80E watermaker includes a three-year factory
warranty and a long history of outstanding customer support. Our reputation for providing a
quality product, along with service when and where you need it, is unequaled in the industry. Of
course, you may never need us—but, if you do, we’ll be there.
