I. GENERal
HQX(B), HQXL(B) pump is a horizontal self-suction gas-liquid mixing p-ump. HQX(B)
is connected with special motor directly. HQXL(B)) is connected with standard motor
by coupling. All the flow parts of the pump is made of stainless steel by precise
molding technology.
The suction inlet of the pump can suck gas by negative pressure, so it is not needed
to use gas compressor of gas jet. The quickly rotating impeller mix the gas and the
liquid, so mixer is not needed. Because of the mixing by added pressure in the volute,
gas and liquid dissolves with each other c¬ompletely. The dissolution efficiency
arrives to 80100%, so big added pr¬essure gas tank or expensive reactor tower is
not needed to get high conce¬ntration solution. One gas-liquid mixing pump can
suck, mix, dissolve gas and liquid. And pump the high concentration solution to the
application pl¬ace directly. Therefore, the usage of the pump can improve the making
eff¬iciency of gas-liquid solution, simplify making device, save space, decrea¬se first
investment cost, save operation and maintenance cost.
II. applIcatIONS
The pump is applied to transfer liquid, mix gas and liquid, circulate and boost.
Typical application:
· Gas suspension treating equipment, ozone water making equipment, heavy-
oxygen-enriched water making equipment and biological treating e¬quipment.
· Transfer of heating or cooling medium for various temperature adju-sting devices.
· Various filters;
· Sucking from underground tank or high pressure transferring low-vi-scosity liquid
such as gasoline, diluents, all kinds of solvent.
· Misting treatment of clear water, pure water, foods, chemical solution and waste
solution.
· Strict applications(intermittent running, water hammer, abrupt varia-tion in hydraulic
pressure): such as small scale stream boiler., high building water supply, high
pressure water injection to high pressure tank and suction from vacuum tank.
· Sampling from river or tank, transferring foaming liquid, transfer li-quid in long and
horizontal pipeline, where gas pockets likely occur.
III. OpERatING cONDItIONS
· Thin, clean, low-viscosity liquid;
· PH Value: 3-9
· Liquid temperature: -15°C — +120°C
· Ambient temperature: Max +40°C
· Gas liquid volume comparison: 1:9 ( Gas suction quantity is 8%-10%)
· Self-priming height is 9-NPSH(m)
