3HP VFD for pump - AC1000
3HP VFD for pump For Sale, Most Competitive Price, Fast Delivery, Custom Service, Wholesale 3HP VFD for pump, Made in China, High Quality Products!, China VFD, Variable Frequency Drive Supplier, Manufacturer.
Gear pumps are economical if in brass but if in SS 316, cost is higher. Variable frequency drive size of pump will also affect the price, we sell gear pumps.
What we need to select a pump normally is these specs.
Chemical (type)
Concentration %
Operating temperature
flow (minimum, target, max)
Motor voltage
Continuos or cycle
Need a 3hp VFD
THD (total head discharge)
Size of piping suction and discharge
For acids without solids in suspension mag 3hp VFD pumps are the best solution for quality and price. The cost obviously depends on the size of the pump. If you need an alternative to a gear pump we suggest you a sliding vane pump because you have the same performance as a gear pump and the all the advantages of a hermetic mag variable frequency drive pump. All vfd manufacturers state very clearly that the PERFORMANCE CURVES are valid for liquids having a specific gravity of that of water. For liquids with higher SG the flow rate drops in an almost proportional manner with increasing SG.
The HYDRAULIC POWER of the pump is directly proportional to the density of the fluid which means, if you take into account motor and axle losses, that it should be almost double than in the case of water.
There is no pump in the world that would ignore the SG, not to mention the increased viscocity of the fluid.
This has nothing to do with electrical power but with hydraulic performance of the single phase to three phase drives.
Even if your motor meets the power requirements the pump will not deliver if it& acute;s sized according to water specifications. Follow VFD on Facebook.

VFD drives, also known as ac drives and VFDs, are widely used in HVAC systems, pumps and conveyors. An ac drive controls the rotational speed of an electric alternating current (AC) motor by adjusting both voltage and frequency of the electrical power supplied to the ac motor.
The efficient way of cutting down the electricity cost on these motors is to adjust the frequency or speed of operation for the ac motor when big power AC motor is being used. It is the general purpose of the variable frequency drives (VFD) being used for. Electric motors that do not adjust their frequency are limited to operate at the maximum frequency all the times, even when not so much power demand. The ability to adjust the frequency when less power is needed, and also can achieve full power running of the motor can improve efficiency, electricity savings, and optimize the motor-driven process. The energy savings from a frequency inverter can be dramatic, with common energy savings of fifty percent or more. Another advantage of using variable frequency drive is their ability to extend the speed range of the ac motor by being able to have adjustable frequency up to 4000 Hz rather than the normal maximum of 50/60 Hz. However, operation of motors at speeds above their rated operating speeds must be checked and approved by the motor manufacturer. Most ac drives are often programmable and allow the operator to select the conditions that are most suitable for their particular application.
