4 Building Services: Water Supply Minimum flow for pump in manual mode Configuration and function Minimum flow per pump in manual mode Pump ya-eco VP Control unit Pump Baseplate 2 4 Control cabinet Collecting line Design Fully automatic pressure booster package system, with 2 to 3 vertical high-pressure pumps and continuously variable speed adjustment of each pump for fully electronic control of the required supply pressure, with two standard volt-free changeover contacts for fault indication. Function Automatic mode Either two or three pumps (3) are controlled and monitored by a micro-processor control unit (1). Each pump is connected to a frequency inverter and controlled by the control unit so as to ensure a constant discharge pressure of the pressure booster system. As the demand increases or decreases, peak load pumps are started and stopped automatically. As soon as the demand increases again after one pump has been stopped, another pump which has not been in operation before is started up. When the last pump has been stopped and the demand increases again, the next pump in line is started up in variable-speed operation. The stand-by pump is also included in the alternating cycle. The standard setting is for the pressure booster system to start automatically as a function of pressure; the actual pressure is measured by an analog pressure measuring device (pressure transmitter). The function of this pressure transmitter is monitored (live-zero). As long as the pressure booster system is in operation, the pumps are started and stopped as a function of demand (standard setting). In this way it is ensured that the individual pumps operate only in line with the actual demand. The use of variable-speed pumps reduces wear as well as the pumps' frequency of starts in parallel operation. If a duty pump fails, the next pump is started up immediately and a fault is output, which can be reported via volt-free contacts (e.g. to the control station). If the demand drops towards, the pressure booster system slowly runs down to the stop point. The operating status is displayed via LEDs. Function Manual mode In exceptional cases, the system can also be operated in manual mode. 4 ya-eco VP Movitec 2B Movitec 4B Movitec 6B Movitec 1B Movitec 15B Minimum flow per pump in manual mode [l/h] Materials Overview of available materials Component Inlet casing Discharge casing ydraulic system Mechanical seal Primary ring Mating ring Elastomer Baseplate ydraulic design Distributor pipe Valves Membrane-type accumulator Membrane Material Stainless steel Stainless steel Stainless steel Complies with EN Silicon carbide ard carbon EPDM Steel, powder-coated Stainless steel Copper base alloy/brass DVGW-approved Connection made of stainless steel, flow through valve to DIN Approved for drinking water Product benefits Energy-efficient operation and constant pressure ensured by speed control of all pumps (all systems non-compliant with Drinking Water Directive, except for single-pump systems) Ease of use and fully automatic control by BoosterControl Advanced Corrosion-resistant by using high-quality stainless steel Ready-to-connect baseplate-mounted package system Pumps mounted on the baseplate on anti-vibration pads Suitable for drinking water installations, manufactured under stringent hygienic conditions
