Key Features
- Variable speed drive EPIC - single phase supply (1-230V-in, 3-230V-out)
- Three-phase horizontal pump (PENTAX U3S-120/6T)
- Stainless steel 5-way connector with built-in non return valve
- Pressure sensor (transducer)
- Pressure gauge (glycerine filled)
- 8 liters diaphragm pressure tank
- Cable with 3 pin plug
Functioning
If the pressure in the network drops, the pump will gradually speed up to provide the set with more pressure. When the water demand decreases, the pressure will rise causing the pump speed to slow down and eventually stop the pump if the demand ceases. The pump will remain on standby waiting to start at the next water demand.
Benefits
- Constant Pressure at Every Delivery Point: Whether using 1 tap or 5 taps, the exact same pressure is delivered. This is achieved through the use of a variable speed drive (EPIC), which adjusts according to demand.
- Stainless Steel Construction: The pump is built from high-quality stainless steel for durability and corrosion resistance.
- Safety: The integrated input-filter prevents disturbances in the domestic network, ensuring reliable operation. It complies with EMC Directives, limiting electromagnetic emissions to avoid interference with radio and telecommunication signals.
- Comfort: The ULTRA S pumps are designed for nearly noiseless operation. Due to the smart EPIC regulation, the pump rarely runs at maximum speed, ensuring quiet performance while still meeting the desired hydraulic requirements.
- Electricity Savings: The system can save up to 40% in electricity usage compared to conventional speed control systems.
- Longer Unit and Hydraulic System Life: By running at lower RPMs, wear and tear is minimized, leading to extended lifespan of both the pump and the hydraulic system.
- Variety of Applications and Performance: Thanks to the EPIC variable speed drive directly connected to the motor terminal, the pump offers a broad range of hydraulic performance in terms of both pressure and water flow, adaptable to various applications.
- Built-in Soft Ramp-up & Ramp-down Capability: The EPIC drive includes soft ramp-up and ramp-down features, which reduce consumption peaks and extend system durability.
- Built-in Protection Against Dry Running and Overload: The system includes protection against dry running and overload. (Note: Incoming supply protection is available upon request).
- Auxiliary Input for Additional Functions: EPIC features an auxiliary input that can be used for float switches, alarms, and other devices.
- Simplified Calibration: EPIC is the easiest variable speed drive to calibrate. Each model comes pre-calibrated to the pump’s best efficiency point (B.E.P.) but can be adjusted to meet specific pressure requirements.
