Centrifugal Pump
OBWS
WESCO PUMP
APPLICATIONS AND USE
- I'st called a wesco pump which is a boiler feed water pump with OBWS type and largely divided a suction discharged casing, casing cover, impeller and bearing housing.
- Furthermore, the pump is never an axis impellent power, long life span and it's very good at small flux high head due to a high accuracy than others.
- Boiler feed water
- For transfer oil
- For assistance fire hydrant and spring cooler
- For all industries and general water supply
- For hillside transfer
- For special chemicals
STRUCTURE AND FEATURE
- It's very suitable for boiler water supply.
- It's easy to install and maintain with small size and a wider operation range than others.
- No need to use a jet pump as it can provide maximum 80°C degrees of water temperature with suction head for water supply.
- Need a high pressure and an inexpensive price with singlestage type.
- Do not set a slag in a pump when welding for plumbing. (Can affect impeller damages)
- Please operate it after put water in a pump without no-load operation. (Can cause a rotation inability)
- Do not operate it in a higher pressure than specification point. (Can cause a motor overload)
