The APKD is an excellent choice for essential services with limited NPSHa since it has been field tested in some of the most demanding applications on the planet. The design has been optimised, resulting in remarkable performance characteristics and highly reliable operation, both of which are the result of modern engineering methods and technology. The APKD is intended to meet the application needs of clients while lowering the overall cost of pump ownership by providing four impeller hydraulics that enable for finely tailored hydraulic selection.
APKD Double-Case, Double Suction Vertical Pump Typical Applications
- Condensate
- Heater drain
- Booster for pipeline
- Stable hydraulic performance and low operating costs.
Benefits of Double-Suction First-Stage Impeller
- Reduces NPSHr and minimizes cavitation risk.
- Meets Hydraulic Institute standards for suction-specific speed.
- Minimizes radial loads, extending bearing life.
- Heavy-Duty Discharge Head maintains motor alignment and supports liquid end and column.
- Keyed Intermediate-Stage Impellers secure with lock collars for easy maintenance.
- Versatile Seal Chamber accommodates various seal types.
- Suction Can ensures acceptable flow conditions.
- Keyed and Flanged Lineshaft Couplings ensure torque transmission.
- Open Lineshaft Construction lubricates lineshaft bearings.
Performance benefits include stable hydraulic performance across a wide operating range, low energy consumption, low first-stage impeller peripheral velocity, low axial thrust for extended thrust bearing life, twin-volute design with low radial loads, compact suction can design and low vibration levels.
