This is a perfect watermaker. Compact, lightweight, and easy to
operate, these units will supply emergency drinking water to help
prevent dehydration or even loss of life.
We offers a wide variety of water
filtration and purification products suitable for any need. This
allows outdoor enthusiasts and travelers to take along products for
making their own drinking water when preparing their trips.
Portable manual desalinator is a patented product,
seawater can be purified to drinking water by manual
operating. It’s mainly composed by high
pressure pump and sea water reverse osmosis(SWRO). Because of
higher osmotic pressure of seawater, as fresh
water be made, high pressure must be forced against the
SWRO, so the high-quality pump must be
needed. Our manual pump with optimum dual-pistons
structure, can generate high pressure, extremely reliable and
long life with replaceable UF pre-filter.
Feature
High pressing pump with dual-pistons structure, compact
dimensions and fine space for it anywhere.
Unique exhaust valve designed, it can not only
discharge the air in the pump, but also work as suction pump.
The device can be worked properly whatever its
attitude: vertical, horizontal or tilt.
High energy efficiency, pumping does not require much
effort.
Can be operated manually, not dependent on
electricity.
Durable design, extremely reliable and long life
Application
Apply to all kinds of emergency cases for fresh water
supply: field survival, island investigation, outdoor adventure,
etc；
The hand worked model can provide fresh water supply
temporarily when other devices do not work；
Can be used in all kinds of small boats, life raft,
the lifeboat... to provide drinking water；
Can be used for inland bitter, brackish and salty
water treatment

others；
Technology：UF cartridge + reverse osmosis for
seawater；
Permeate Flow：4-5 L/h（25℃，the salt content of
3.2%）
Height to Carry Water: 5 m；
Dimensions: 45 x 7 x 7 cm；
GW/NW： 3.3 /3.0 KG；
Principle
As shown in the followed figure, the pump design as double
piston. When the handle get pressed up and down, one piston absorb
the seawater, meanwhile other piston press the part of seawater
pass through the reverse osmosis, making output water efficient,
continuous and stable; When the handle does not work, the pressure
in the pump body could be able to get quickly released to ensure
safety of the device, and also to improve the reliability of the
product; The exhaust valve has unique design that when the switch
of exhaust valve is open and meantime the handle get pressed, the
water flows from the inlet to outlet through external of reverse
osmosis membrane in the body. At this time, the device can be used
as water pump and the pumping height can achieve 5-6 meters; When
no air get discharged out of exhaust water pipe, fresh
water could be produced after closing the switch on the
exhaust valve.
