Read this manual carefully
before install, start the pump.
I. AppLICATIONS AND CONDITIONS
HF, HX, HN are non-self-priming light horizontal multistage
centrifugal pump (abbr. as pump in the following). They are efficient, low noise,
little corrosive tolerance, compact structure, good looking, small volume,
light weight, etc.
1. Applications
· Pumped liquids: Low viscosity, neutral, non-explosive liquids, not
containing so lid particles or fibres. The liquid must not attack the pump
materials chemically. (Oil or the liquid mainly consisted of oil can be pumped
by special type of pumps);
· Circulation for air condition system;
· Cooling system;
· Water treatment, purification system;
· Industry cleaning system;
· Liquid transferring, circulation, boosting;
· Hot or cold water;
· Feed proportioning system of food, drinking, agriculture, etc.
2. Operation conditions
· Liquid temperature: Normal temperature type -15ºC~+70ºC ;
Hot water type -15ºC ~+ 110ºC;
· Flow range: 0.5~28 m
3
/h
· Max pressure: 10 bar
· Liquid pH range: pH5 ~9
· Max ambient temperature: +40ºC
· The Max suction pressure is limited by max operating pressure;
· Min inlet pressure: Refer to HDROO catalogue.
Caution: When pumping liquids with a density and/or viscosity higher
than that of water, use motors with correspondingly higher outputs, if
required.
