Ship SN Series Three Screw Pump
Main Feature
SN three – spindle screw pump is of self – priming. Because of the unit assembly system, every pump can be supplied as a cartridge pump for foot – flange or wall mounting, in pedestal – bracket or submersible design. According to the delivery medium (heated or cooled), designs are also available.
Usage
For the handling of oil and medium with lubricating properties.
Application
- In heating techniques as fuel oil and medium with lubricating properties.
- In the engineering industry as hydraulic – and telemotor pumps.
- In the chemical and food industry as cargo – transfer or supply pumps.
- In the marine field as transfer – booster – fuel oil pumps as well as for ship hydraulics.
Characteristics
- Stable Hydraulic Balance: The rotor has hydraulic balance, with small vibration and low noise.
- Stable Output: The output is stable with no pulsation and high efficiency.
- Strong Self – Priming Ability: It has a strong self – priming ability.
- Versatile Component Design: The components adopt a versatile and strong series design, available in multiple installation methods.
- Compact Structure: The structure is compact, with a small volume and light weight, and can work at relatively high speeds.
