3-KVCX

Summary

Product identification

The DAB 3 KVCX series consists of water lifting sets, specifically designed for domestic, civil, agricultural, or industrial applications. These sets feature three vertical multistage centrifugal pumps, ensuring high performance and efficiency.

Key characteristics include compact dimensions, rugged construction, extreme reliability, and very low noise operation.

Operating limits

Maximum obtainable pressure and pressure switch settings vary by model:

• Maximum Pressure Obtainable: Ranges from 4 bar to 10.5 bar.
• Pressure Switch Setting: Ranges from 1.5 – 3.5 bar to 8 – 10 bar.

Electrical

The pump sets are available in single-phase and three-phase configurations, operating at 50 Hz.

• Voltage: 1 X 230 V~ or 3 X 400 V~
• Nominal Power (P2 x 3): Ranges from 0.55 kW to 3 kW.
• Nominal Horsepower (HP x 3): Ranges from 0.75 HP to 4 HP.
• Nominal Current (In x 3): Ranges from 1.4 A to 12 A.

Mechanical / hydraulic

The sets are supplied with tanks and an air supply connector.

• Suction Connection (DNA): 2" 1/2
• Delivery Connection (DNM): 2" 1/2
• Dimension P: The dimensions table lists a dimension 'P' ranging from 109 mm to 385 mm. A diagram for specific models (KVCX 70/120 85/120) also indicates a manifold connection labeled 'P' of 1" 1/4. Please refer to the official PDF for clarification on this dimension and connection type.

Dimensions (in mm) and weights (in Kg) vary by model. See the official PDF for exact tabulated values, but common dimensions are:

• A: 655
• B: 840
• C: 800
• D: 860
• H1: 175
• H2: 1205
• H3: 120
• Total Height (H): Ranges from 940 mm to 1185 mm.
• Weight: Ranges from 109 Kg to 148 Kg (single-phase and three-phase models may have different weights).

Control Panel

The control panel is made of impact-resistant, self-extinguishing plastic with an IP 55 protection rating. It is installed on a column mounted on the pump skid. Features include:

• Main power switch
• Thermal magnetic cut-outs for electric pump protection
• Electric pump starting sequence changeover system
• Low voltage 24V control circuit
• MAN-0-AUT selectors
• Start pushbuttons (for single-phase versions)
• Indicator lights on the front panel
• Three preset pressure switches for pump starting/stopping.

The control panel is prearranged for connection of optional items:

• Pressure switch or float switch kit for dry running protection
• Overpressure cut-out pressure switch kit
