- Pressure boosting for low-pressure systems
- Garden and lawn irrigation
- Small pressure tank installations
Agricultural & Commercial
- Irrigation systems for small to medium properties
- Water well service operations
- OEM equipment integration
- Light industrial water transfer
Technical Advantages
Design Features:
- Peripheral impeller technology for high head generation
- Patented aluminum motor bracket with brass insert prevents impeller seizure
- Cast iron pump body with ISO 228/1 threaded ports
- Epoxy coating on PK 60/60-MD models for corrosion resistance
Operational Benefits:
- Low energy consumption with IE2/IE3 efficiency motors
- Continuous duty rating (S1) for 24/7 operation
- Maximum suction lift: 26 feet (8 m)
- Wide temperature range: 14°F to 140°F (-10°C to +60°C)
Scope & Limitations
Suitable For:
- Clean water only (no abrasive particles)
- Non-chemically aggressive liquids
- Pressures up to 145 psi (10 bar) depending on model
- Ambient temperatures to 104°F (122°F for PK 60)
Not Recommended For:
- Wastewater or sewage
- Liquids containing solids or sediment
- Chemically corrosive fluids
- High-volume industrial applications
Model Selection Guide
| Application | Recommended Models | Rationale |
|---|---|---|
| Basic home water supply | PK 60, PK 60-MD | Adequate pressure, economical |
| Multi-story buildings | PK 70, PK 80 | Higher head capability |
| Large homes/small farms | PK 90, PK 100 | Balanced flow and pressure |
| Commercial irrigation | PK 200, PK 300 | Maximum capacity |
Key Differentiators
PK 60-MD Model: Medium duty variant with enhanced performance curve - better suited for consistent high-demand applications.
Voltage Options: Available in single-phase (110V, 127V, 230V) and three-phase (220/380V, 230/460V) configurations for flexibility.
Certification & Warranty: DNV ISO 9001 certified quality management, 2-year warranty, compliant with EN/IEC safety standards.
Optimization Recommendations
- Match to demand curve: Select model where operating point falls in middle third of performance curve for optimal efficiency
- Consider system pressure: Choose working pressure rating with 20% safety margin
- Evaluate duty cycle: All models support continuous operation but size for peak demand
- Plan for maintenance: Mechanical seal and bearing specifications provided for service planning
This pump series excels in residential and light commercial clean water applications requiring high pressure relative to flow, making them ideal for pressure boosting and elevated storage filling rather than high-volume transfer applications.
