Product DescriptionProduct DescriptionTQG Booster Pump Set TQG is an innovative energy-efficient pumping solution that integrates frequency control technology with frequency converter and pump-motor units. By adjusting the output frequency of the inverter via microcomputer control, TQG system regulates the speed of the pump motor, achieving closed-loop pressure stabilization in the user's pipeline network. The system automatically maintains a constant preset pressure: when water demand increases, the frequency rises, speeding up the pump; when demand decreases, the frequency drops, slowing down the pump. This ensures a stable and sufficient water supply pressure and flow at all times.Vertical multistage pump unit Horizontal pump unit Vertical Multistage pump unitConfiguration:Pump: 2-4 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Common Steel BASEConfiguration:Pump: 2-4 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Common Steel BASEConfiguration:Pump: 2-4 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Common Steel BASEPumps& Manifolds (No pressure tank)Pumps& Manifolds (No pressure tank)Pumps& Manifolds (with pressure tank)Configuration:Pump: Vertical Multistage 2-4 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Common Steel BASEConfiguration:Pump: Vertical Multistage 2-4 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Controller: Built-in VFD and pressure switch Common Steel BASEConfiguration:Pump: Vertical Multistage 1 unitsPiping& Fitting: Suction and discharge manifolds & Check valves, Gate valve, bender,etc.Controller: Built-in VFD and pressure switch Common Steel BASEModel MeaningSpecificationVertical Inline Multistage pumpHorizontal End Suction pump Vertical Inline Single Stage pumpControllerMounting:1.

Copper Structure DrawingSystem Composition:- Pump unit(s) (centrifugal type) - Hydropneumatic accumulator (diaphragm-type pressure vessel) - Pressure transducer(4-20mA output) - Frequency conversion control cabinet(with PID algorithm) - Pipe and fitting and Common steel base This integrated system maintains user-defined parameters with ±0.01MPa precision. Working PrincipleOperational Logic-Multi-Pump CoordinationThe variable frequency water supply system maintains constant pipeline pressure by adjusting pump speed. When the detected pressure at the outlet drops below the preset activation threshold, the system automatically modulates pump speed to stabilize output pressure. - If pressure remains below the setpoint at full speed (50Hz), the system sequentially activates Pump #2 and Pump #3. - As water demand decreases and pressure rises, pump speeds gradually reduce. - When speeds reach the minimum threshold, pumps shut down in reverse order (#3 → #2 → #1). Performance Highlights:- Dual-purpose operation: Seamlessly handles both domestic and firefighting demands - Adaptive logic: Intelligent pump sequencing maximizes equipment lifespan - Zero-intervention maintenance: Self-diagnostic protocols minimize downtime Company Profile
