BENEFITS
- Maintain constant pressure at Variable speed.
- Wireless control panel compact in size and space saving.
- friendly interface of adjustable system pressure setting.
- Intelligence systerm leakage compensation.
- Soft starting & stopping for elimination of water hammer.
- Built in pump dry run protection and full protection for motor
and inverter.
- Multi-freuncy inverters for reliable function
- LED indicators for normal,running and fault.
- Auto-record of systerm fault.
- Automatic change over function of alternating and parallel for
Multi-pump system. The standard set is maximum for 4 pumps.
And larger amount can be pffered by request.
- Fan less cooling system for slient operation.
- Suitable for outdoor installation.
- Great energy savings.

The energy is the cube of the speed . The V.S.D.
Control SYS only adjust speed by demands for
Flow , so it improves the full speed running waste.
And it will substantially save the energy.
DESIGN
- SMX /LMX /HSMX /HLMX Series contains pump,motor,V.S.D.
Contorl SYS ,inverter,pressure tank.check valve,gate,pipes
Connected inside the machine ,bass,and some necessary
Small parts.
- Combination of great engineering technology & friendly user
Interface that requires no special control training for operation
And maintenance.
- SMX /LMX /HSMX /HLMX Series are with integrated the V.S.D.
Control SYS to maintain consists of a pressure controller for
Detection, computation and transmission of the real time
System pressure signal to command the frequency inverter to
Change the supply voltage to the electric motor, thus the pump
Speed is adjusted to maintain the predetermined pressure.
- And more , V.S .D. control SYS is designed for effciency and
Enery savings. It will reduce the power waste. Through the
Calculation beside. It’s easy to understand.
DESCRIPTION

COMPONENT
Constant Pressure Controller0-10/kg &Electrical Technology Contror Panel
Chip device & Point contror
- Integrated pressure transmitter,CPU with PID controller,and digital
Pressure display
- The systerm has enormous ability of calculation to gather all function,
Such as constant control, protection,and fault record...ect,in one
Single chip.No traditional wire line and switchboard.All
Components are very simple which are complx of units with
Different function.
- The adjustment of the pressure is easy and that simply turning
The point can change the pressure.it’s easy to operate,maintain,
And replace any of the unit even for people didn’t know about
Control.
INVERTER
- High quality frequency inverter for converting the supply voltage to
The motor and thus changes the rotation speed,multi-frequency
Inverter makes the control untit more reliable.
Interface Card of Alternating Parallel Function
Interface card is for automatic change over function of alternating
And paraller for multi-pump systerm. The standard set is maximum
For4 pumps,And larger amount can be offered by request.
