CRTR4 Leshan inverter pump the Shanghai Spring Jiang professional design manufacture and sale of quality excellence Leshan frequency rotor pump rotor by means of pressure (or layers): With the pressure of the water pipe network equipment running supercharger on this basis, and from ordinary reservoir reduces water absorption compared to running the pump station, or reduce speed and to save energy. Power outages continue to water: a power circuit, the system automatically switches to the municipal tap water pressure water supply. Health: over-current flow passage components are made of stainless steel and other food grade material. Box-type negative pressure device to ensure that the the vertical diaphragm regulator tank storage water through the user automatically every day more innovative, closed negative pressure device in real-time replacement to ensure water hygiene. Energy saving: The system does not reservoir storage facilities and other civil engineering, saving footprint. The system has been running at high efficiency. Energy savings of 60% or more. Municipal pipe network pressure, pressure can be run simply fill in the municipal pressure based on. The system fully automatic operation without special duty; compounded by reservoirs and other the civil water storage facilities, water treatment instrument, eliminating the need for regular cleaning and disinfection work. Therefore, the energy-saving effect is very significant. 6526 Supply spring ginger the LVWS type VVVF no negative pressure water supply equipment, water supply equipment, water supply equipment spring ginger the LVWS type frequency conversion governor no negative pressure water supply equipment Product Description Product Overview the LVWS type VVVF no negative pressure water supply equipment used is imported and programmable control form a closed-loop control systems, drives, and reasonable control lines and pump unit, the water supply network to maintain a constant pressure. Select the Leshan-conversion rotor pump, please look for the Shanghai Spring Ginger brand.
