21. Household Booster Pumps
Features:
The automatic switch adopts electonics theory,
controlled by water current. It boosts pressure
automatically when the tap is on and turned off
when the tap is off. It is used conveniently and also
saves power.
Its copper pump body, copper impeller and
stainless steel shaft are corrosion-resistant,
stainless. The whole pump is sealed well and the
conveyed water won’t be unhealthy. It’s total
suction lift is high. Flow rate is large.
It starts well, switches sensitively and
automatically, and produces low noise. It also is
designed to be low temperature, small volume,
delicate appearance and long-time using. 15 GZ
boasts self-suction function.
Body is designed to be gathered with automatic
switch so the fixing is more convenient.
22. The automatic switch adopts the electric circuitry to control, less trouble. The
impeller adopts the centrigual construction, mute design and some
materious of the parts are copper.
5. the water-supply is much more sanitary because of the no-rust. The pump
inside has the fan-cooling device to much more effectively to
cool the temperature of the motor and long-time using.
MAIN USE:
This pump solves the problem of inadequate water causing no lit fire because
when the tap water is of low pressure, the pump can boost pressure. It can
also boost pressure for solar water heaters, boost pressure and circulate
water for industrial equipment, and increase oxygen for rearing ponds or fish
tanks.
GR hot water pump boost pressure and circulate hotwater for boilers besides
above using. GR hot-water for boilers besides above using. GR hot-water type
also can be used for circulation and pressurization of hot water. 15GZ best
feature is that it can suck tap water from one or two floor below directly. So it
completely solves the problem that the higher floors don’t have water while
the lower floor has.
