The KSB Calio Z pump is a high-performance twin pump with a wet rotor (sealed electric pump).
Maintenance-free. PN16. Auxiliary connection: pipeline Rp 1 1/4, pump G 2. 1000 - 4500 rpm. Power 3.5 - 220 (440) Watts.
The pressure is 16 bar. Highly efficient electric motor with smooth differential pressure adjustment. Synchronous electric motor with permanent magnet rotor and electronic switching. Built-in motor protection relay. 1~230 Vacthe current is +/- 10%. The frequency is 50 Hz/60 Hz. The degree of protection is IPX4D. Heat resistance class F. Temperature class TF 110. Energy efficiency index EEI ≤ 0.23. Interference emission EN 61000-6-3. Noise immunity EN 61000-6-1. A special sliding bearing lubricated by the pumped medium.
Threaded or flanged connection.
Operating modes: constant pressure maintenance mode, proportional pressure control, differential pressure adjustment depending on temperature (using KSB ServiceTool only), manual control mode with prescribed setpoint, Eco mode with dynamically adjustable differential pressure. Automatic functions: smooth adjustment of the rotation speed depending on the operating mode, 0 – 10 V with an external prescribed value of differential pressure /speed, 0-10 V input for the actual temperature value or the actual value of differential pressure, pump change after 24 hours of operation of one pump, standby mode is carried out by automatically starting the backup pump at the outlet failure of the working pump, two-pump operation mode, peak load mode, reduced supply at night, external start/stop, unlock function, automatic air removal function, smooth start, full motor protection with integrated opening electronics. Manual functions: setting operating modes, setting the setpoint of the differential pressure, setting the speed stage, locking the control panel, alarm and indication functions, alternating display of supply, pressure and power consumption, display of the operating mode on the display, display of the error code on the display, configurable general fault and operating mode messages (potential-free switching contacts), serial digital interface Modbus RTU, service connector for KSB ServiceTool. Main applications: heating, ventilation, air conditioning and circulation systems, 1 and 2-pipe systems, floor heating, boiler circulation circuits or primary water heater loading circuits, solar installations, heat pumps.
Pumped media: hot water for heating systems according to VDI 2035, highly viscous media (water-glycol mixture, max. The ratio is 1:1). Reduction of investment and commissioning costs due to the "All-in" concept. Easy operation of the pressure/speed regulators in combination with an integrated display and symbols indicating the operating mode.
High operational availability due to the two-pump operation mode and built-in protective functions. The new Eco mode of operation allows additional savings of more than 40% compared to proportional pressure control.
