DAB 2 ESYBOX MAX 60/120 T pressure station with two units on base 2 ESYDOCK MAX – 3 × 380–480 V – SPECIAL OFFER

Product detailed description

Double Pump Station ESYBOX MAX

The DAB 2 ESYBOX MAX 60/120 T assembly combines two ESYBOX MAX 60/120 T pumping units on a dual base 2 ESYDOCK MAX; according to IVAR, the complete assembly also includes a control panel and a bracket. It is designed to increase water pressure in residential homes, commercial buildings, and high-rise buildings. According to the manufacturer, the combined operation of two units provides high performance with up to 50% less space requirement than traditional systems of comparable performance.

After setting up the first pump, the second one synchronizes automatically; the control panel alternates the pumps, starts both at higher consumption, and one can be set as a backup. For units with 3 × 380–480 V power supply, the manufacturer provides the E2G7 T 400V control panel with thermal-magnetic circuit breakers, which can be mounted on the wall or attached to the units via a bracket. The station is 811 mm wide, 384 mm deep, and 766 mm high (1172 mm with the panel on the bracket), with 2" internal thread connections.

Station Performance

According to the manufacturer's performance table, the pair of 60/120 units achieves a head of 69 m at a flow rate of 12 m³/h, 53 m at 16.8 m³/h, 37.2 m at 22.8 m³/h, and 3.9 m at 34.8 m³/h. For each unit, the maximum differential pressure is 6.7 bar, the maximum power consumption P1 is 2.65 kW (3.5 HP), and the rated current is 4.4 A.

Construction and Control

• vertical multi-stage centrifugal pump with three impellers made of technopolymer with steel wear rings, a check valve on the discharge, and a 2-liter expansion tank
• permanent magnet motor cooled by pumped water, motor housing and shaft made of stainless steel, efficiency at the level of IE5 class according to internal manufacturer tests
• frequency converter with pressure sensors on the suction and discharge maintains a constant pressure of 1–12 bar (3 bar from the factory)
• large display, Wi-Fi and Bluetooth, DConnect app for settings, alarms, and consumption overview
• protections against dry running, overheating, freezing, blocking, cycling, and abnormal current or voltage
• esy I/O module (accessory) for connection to a building management system (BMS)

Operating Conditions

Clean, non-viscous, non-aggressive, and chemically neutral water without solid and abrasive particles up to +50 °C, ambient temperature up to +55 °C, inlet pressure up to 5 bar, rated pressure PN 12. The pump is not self-priming – it draws water from a tank or boosts pressure from a water supply; when installed above the water level, the suction lift with a check valve is up to 4 m. Fixed installation in a vertical position, motor protection IPX5, insulation class F. Thanks to WRAS, ACS, and NSF61 certificates, it is also suitable for potable water.

Electrical wiring and commissioning should be carried out by a qualified professional; the supply must be protected by a residual current device with I Δn ≤ 30 mA.

Frequently Asked Questions

What does the 2 ESYBOX MAX assembly include?
Two ESYBOX MAX 60/120 T pumping units and a dual connection base 2 ESYDOCK MAX. According to IVAR, the complete assembly also includes a control panel and a bracket.

What flow rate can the station achieve?
According to the manufacturer's performance table, the pair of 60/120 units can deliver up to 34.8 m³/h at a discharge head of 3.9 m. The full discharge head of 69 m is maintained up to a flow rate of 12 m³/h.

How do the pumps in the station work together?
After setting up the first unit, the second one synchronizes automatically. The control panel alternates the pumps, starts them simultaneously at higher consumption, and one can be set as a backup.

What kind of water can be pumped?
Clean, non-viscous, non-aggressive, and chemically neutral water without solid and abrasive particles with a temperature up to +50 °C. Thanks to WRAS, ACS, and NSF61 certificates, ESYBOX MAX is also suitable for potable water.
