System Description
The Katadyn PowerSurvivor 40E 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 Assembly: 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. A grease lubricated 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). The high pressure forces product
freshwater through a semipermeable membrane located in the membrane housing. All of these main
components have been integrated into a single, compact piece of equipment — with low power
consumption, quiet operation and a small footprint.
Prefilter Assembly: The prefilter assembly consists of one prefilter housing and a standard
30-micron prefilter element constructed of polyester fibers. Two standard elements are included 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
from the pump, 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 two input sources for the prefilter assembly (and pump):
Clean seawater during normal operation
An alternate intake line for inputting membrane preservative or a cleaning solution
The product 3-way valve allows easy selection between the two required destinations for the product
freshwater:
A freshwater collection tank for normal operation
A convenient drain location for testing and discarding product freshwater,
membrane preservative and cleaners
Note: If you collect and discard the product freshwater at the same location, manually directing the
output from the product freshwater hose may be the most practical approach. In this case, the
product 3-way valve need not be installed.
Hoses and Hardware: Each PowerSurvivor 40E watermaker is shipped with hardware
sufficient to perform a normal installation. The 3/8" I.D. reinforced plastic hose is used for seawater
intake and reject brine. The smaller, 3/16" I.D. clear plastic hose is for routing product freshwater.
There are also hose clamps and mounting bracket hardware for the prefilter assembly.
Customer-supplied Equipment: Every installation represents a unique challenge. You or your
installer will have to provide:
a reliable source of clean seawater for input to the prefilter 3-way valve
plumbing to an appropriate drain location for the reject brine water
a plumbing solution for your freshwater collection tank
Our Promise: Every Katadyn PowerSurvivor 40E 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.
