CHDF Series Horizontal Multistage Pump

Description

Horizontal multistage pump

CHDF series subsection  type horizontal multistage centrifugal pumps adopt axial inlet and radial outlet, attach  with long shaft eleclric  motor.All flow passages parts made of stainless steel.The pump warm welcome for compact structure, high efficiency and reliable quality etc.

Application

CHDF series pumps are widely used in industrial and domestic field.

Water supply or boosting.

Air-conditioning system or cooling system.

Industrial cleaning or washing system.

Water treatment system or Water purification system.

Aquiculture or Fertilizing.

Environmental protection application.

Other industrial or domestic appllications.

Operation condition                   

Medium temperature:

Normal temperature type: -15℃~+70℃

Hot watertype: +70℃~+110℃

Ambient temperature: up to +40℃

Max. Operation pressure: 10bar

Max. Inlet pressure is limited by the Max. Operation pressure

Electric motor

Total -enclosed Fan-cooled two-pole standard motor

Aluminum housing motor

Protection class:IP55,insulation c1ass: F

Standard voltage:60Hz:

1X220-240V

3X220-240V

3X380-415V

Medium

Thin and clean, non-flammable and nonl-explosive medium without solid granules or fibres.

Mineral  water, soft water pure water, edible vegetable oil and other slight chemical  medium.

When thedensity orviscosity ofmedium is 1arger than that of water, it is necessary to choose a high-power driving motor.

Whether a specific medium is suitab1e for the pump depends on many factors. among which  the most  important ones  arechlorine content, PH-value, temperature solvent and oil content etc.

Curve conditions

Following conditions are suitable for the perforrnance curves shown above.

All the performance curves are based on the measured value of a motor at constant speed of 3500rpm.

Curve tollerance in conformity with ISO9906 appendix A.

Measurement is done with 20℃ air-free water kinematic viscositY of 1 mm²/sec.

The operation of pump shall refer to the perfomance region described by the thickcned curve to prevent overheating due too small folw rate or overload of molor due to too large flow rate.
