DAB K 35/100 Auto / 1.1KW 230V Twin-Impeller Centrifugal Pump With Automatic Pump Controller
15901
The DAB K 35/100 Auto is a twin-impeller centrifugal pump built for pressurisation and general water supply. Two impellers in series produce noticeably more head than a single-impeller pump of the same power, in a robust cast iron casing. It is rated at 1.1 kW (1.5 HP) on 1 x 220-240 V ~ 50 Hz, delivering a maximum flow of 7.2 m³/h and a maximum head of 38.5 m.
This version is supplied fitted with an automatic pump controller (press control), which starts the pump the moment a tap is opened and stops it when flow ceases. It replaces a pressure vessel and pressure switch, and protects the pump by shutting it down if the water supply runs dry.
Applications
- Pressurisation units in water systems
- Filling of pressure vessels and tanks
- Sprinkler and irrigation systems
- General water supply in domestic, civil and industrial environments
- Booster duty where steady pressure at moderate flow is required
Pump Construction
- Twin-impeller design for higher head than a comparable single-impeller pump
- Pump body and motor support in cast iron for durability and quiet running
- Technopolymer impellers
- Carbon / ceramic mechanical seal
- Install horizontal or vertical, provided the motor is always above the pump
Motor Construction
- Closed asynchronous type with external ventilation cooling
- Rotor on permanently lubricated, oversized ball bearings for low noise and durability
- Standard built-in thermo-amperometric protection
- Capacitor permanently fitted on single phase versions
- Construction according to CEI 2-3
Automatic Pump Controller
- Starts the pump automatically when a tap or outlet is opened
- Stops the pump automatically once flow ceases
- Dry-run protection shuts the pump down if the water supply fails
- Built-in non-return valve prevents backflow
- Removes the need for a pressure vessel and separate pressure switch
- LED indication of power, pump running and fault status
- Manual restart after a dry-run trip
