HU Heavy Duty Processing Pumps

Introduction:

HU heavy duty processing pump is horizontal, single-stage, single-suction overhung centrifugal pump, which is desinged according to API 610 and AI 682, requirement stage A(heavy duty). They are kinds of processing pumps with high reliability, long lifetime, and stable performance, high degree of generalization(same performance curves as HA), high NPSH and efficiency.

Performance:

Applications:

To pump the fluid which is low-temperature or high-temperature, neutral or caustic, clean or with solids, can be applied in:

Refinery, petrochemical industry, coal processing industry.

Chemical industry, fibre industry and general processing industry.

Energy generating plants.

Medium-sized and large heating and air-conditioning plants.

Envrionmental protection engineering.

Structural Featues:

HU heavy duty processing pump is mainly structured with radial split and with feet on centerline. The casing with larger than 80 mm-diameter(including 80mm) is desinged double-volute, which can balance the radial thrust. The pressure chamber forms bu means of the connecting of casing and casing cover, which makes the pump operate safely and reliably.

The pump can be equiped with heat-protection(cooling) sleeve. There is cooling water chamber on the casing cover which reserves the heat of pump chamber and enlarge the application range.

The bearing is lubricated with oil. The constant level oiler is equipped with the bearing house can control oil level automatically. Taper roller bearing is equipped with driven-end to balance the axial trust. There are two kinds of cooling methods:water cooling and wind cooling which can be applied in diiferent operation condition.

Seal chamber is desinged totally according to API682 including ripple seal, single and double-end mechanical seal which can be equipped with various flushing plans. Cooling of baseplate pedestal possible.

The pump rotation direction is CW viewing from the driving side.
