Characteristics
9 1
WEAR RINGS Casing wear rings are standard and replaceable on all pumps. Impeller wear ring are optional.
2
IMPELLER All impellers are double suction, dynamically balanced and held in place by separate nuts. (investment casting and sand casting manufacturing).
3
BEARING HOUSING 360° bearing housing arrangement to ensure mechanical stability and low vibration levels. Design allows to use the housing for packing (Standard seal) or mechanical seal (Optional seal).
4
BEARINGS Interchangeable line and thrust bearings (conservatively rated at 100,000 hours“plus” bearing life) guarantee maximum life at minimum maintenance cost. Either oil or grease lubrication available.
5
CASING SEALING SYSTEM Innovative sealing system allows metal to metal contact ensuring a perfect rotor-casing alignment, improved sealing capacity and ease of field maintenance.
MECHANICAL STRENGTH Provided with ribs and connection bosses to ensure mechanical strength during hydrostatic test and normal operation.
6
FLANGES Suction and discharge connections all on the same center line for piping ease.
Images for general arrangement use only, not certified for construction.

SHAFT SLEEVE Separate shaft nuts feature provides the greatest simplification of sleeve replacement. Sleeves are sealed to shaft by an “O” ring to prevent leakage and subsequent erosion. 11-13% chrome sleeves are available for extended sleeve life on packing.
SPLIT CASE
Description • Single or multi-stage horizontal centrifugal pump • Horizontally split case, single-volute or double-volute (some HSC sizes) minimizes thrust loads and allow operation over a wide range of capacities • Flanged connections • Enclosed impellers, double suction provides hydraulic balance eliminating axial thrust
7
• Clockwise or counterclockwise rotation SHAFT A rigid shaft combined with double volute casing - results in low shaft deflection at all operating points. Low deflection reduces packing wear, ring wear and bearing loading, which ultimately results in sustained efficiency and economic operation.
• Oil lubrication bearings • Stuffing box allows mechanical seal option • Horizontal or vertical mounting arrangements available • Foot mounted
Benefits • All HS/ZW pumps can be mounted vertically or horizontally, depending on the requirements of the customer

which assures metal to metal contact.
Multi-Stage Horizontal Split Case From our Industrial Line, the HSM pump is a split case heavy-duty process pump. Unlike our other split case pumps, the HSM type is a two- or four-stage pump which allows higher pressure applications such as petrochemical, chemical, industrial, boiler feed or power plant applications.
Design Features • Oil lubricated bearings • Flanged connections • Stuffing box allows for packing or mechanical seal options.
