Hydro-Pneumatic & Water Supply System
Hydro-Pneumatic & Water Supply System
Product Code : MHN
Product Description

The Control system of MHN is designed and manufactured using sensors, which controls the operation of Hydro Pneumatic Pumps. Wide range of protections in MHN guarantees trouble-free smooth running of system. Depending on applications MHN can be reconfigured for optimum performance.


  • MHN uses separate MCB for each pump, which prevents any damage due to Short Circuits in the system
  • Overload protection is achieved by the standard thermal overload protection provided in the starter separately for each pump. This can be set to desired value depending upon the motor rating
  • Individual equipments are protected from the single phasing by allowing thermal overload relay to trip when the current increases due to single phasing
  • MHN incorporates low-level alarms for the system. It also protects the system from dry running when the suction tank is empty
  • Providing change over from one stand by to another is unique feature of MHN. This ensures that both the pumps are put to equal use
  • The system also allows the stand by pump to be used as an additional pump during peak load
  • MHN continuously displays electrical parameters and the load characteristics of the motor when it is running
  • MHN monitors the “Rapid Cycle” (length of acceptable minimum pump run time) feature and allows for a manual or cycle reset. This means that when a rapid cycle is detected for a frequency set by the system the pump is turned off and it will remain off until it is manually reset. Undetected “short cycling” can lead to multiple problems such as water hammer, contact failure, stripped keys or couplings, broken pump or motor shafts, and ultimately system failure
