Characteristics of cast iron fountain pumps

Characteristics of cast iron fountain pumps
Uses and characteristics:
Scope of application
For enterprises and institutions such as: bath, district heating, geothermal energy companies use power generation, extraction of underground hot water, according to different calibers we have different specifications for the user to choose models. The device low noise, high efficiency and save energy.
Technical Parameters:
1: Allowable operating water temperature range: +5 to +105 ℃
2: Solid impurity content (mass ratio) is not more than 0.01%
3: PH value (pH) 6.5-8.5
4: hydrogen sulfide content of not more than 1.5mg / L
5: chloride ion content of not more than 400mg / L
6: crew must completely invade the water work. Vertical use, select the model diameter and pump models to match, should not use large diameter diameter of small diameter pump, this is not conducive to the motor cooling.
Motor parameters
Submersible motor lead length: 3m. If you need to extend the cable can call us in advance, submersible motor water lubrication, the use of the motor cavity must be filled with clean water, (Note: must be filled otherwise will reduce the motor life) If you forget to add water motor will Rapid burnout.
Motor protection class: IPX8
Electromagnetic wire adopts high temperature waterproof wire.
power supply
380V / 660V, the deviation does not exceed ± 5%, the frequency of 50HZ, the deviation does not exceed ± 1%, if the customer needs a special voltage or special frequency need to inform us in advance.
material
Impeller: cast iron HT200, or tin bronze (various brands) such as: ZCuSn3Zn8Pb6Ni1
Pump housing: cast iron HT200, or stainless steel such as: 2Gr13 .304
Pump shaft: cold-drawn steel chrome-plated, or stainless steel 2Gr13 (1050 ℃ quenched and tempered to enhance the torque)
Motor Seal: Rubber Seal O-Ring; Machine Seal.
Motor expansion regulating bladder rubber material.
Equipment advantages
-1: Careful assembly at the factory ensures fast and reliable on-site installation
-2: single-stage impeller or multi-stage impeller in series, the noise is minimal. Temperature performance, long life.
-3: the crew can completely invade the water work, to avoid the vacuum pump easy to enter the air is not easy to use the drawbacks,
Scope of supply:
Hot water submersible pump unit (including the pump and submersible motor composed of two parts), the outlet matching flange one, 12 × 60 bolts 6. Or configure the corresponding outlet (for users to install hose), the use of maintenance manual 1, 1 copy of certificate of packing list, wooden box packaging.
ATQJ, QH stainless steel submersible pump, pump is a direct one of the wells with submersible pumps, direct submersible operation. Slender structure. Single-stage or multi-stage pump-type wet three-phase asynchronous motor submersible pump. Is designed for agricultural irrigation and drainage, irrigation, industrial and civil construction of the drainage system for ponds, fish ponds, water towers, deep water and high-rise water, fountain.
