Product catalog summary
Product Overview:
The document details the specifications and adjustment procedures for the GENEBRE S.A. Water Pump Pressure Control, model 3780. This device is designed to manage the pressure in water pumps, featuring a plastic protection case with an IP 44 rating.
Specifications:
  • Connection Voltage: 230V, 50-60Hz
  • Maximum Consumption: 12A
  • Maximum Power: 2 HP
  • Maximum Pressure: 4 bar
  • Regulation Field: 0 to 4 bar
  • Factory Default Settings: Starting Pressure - 1.4 bar (±0.3 bar), Shutdown Pressure - 2.8 bar (±0.3 bar), Maximum ΔP - 1.4 bar
  • Maximum Frequency: 60 cycles/min
  • Mechanical Life Cycle: 200,000 cycles
  • Electrical Life Cycle: 30,000 cycles
  • Maximum Temperature: 50ºC
Adjustment Instructions:
The pressure switch is pre-set at the factory with specific default values. Adjustments can be made within specified ranges:
  • Starting Pressure: 1.0 to 2.0 bar
  • Shutdown Pressure: 2.1 to 3.5 bar
  • Maximum ΔP: 1.4 to 1.7 bar
Improper adjustments can reduce the device's lifespan. To adjust, remove the plastic cover and use a tube key to modify the nuts on the regulation devices. Adjustments can be made to either increase or decrease the cut-in and cut-out pressures while maintaining a constant differential.
Dimensions and Weight:
  • Size: 1/4"
  • Dimensions: A - 95mm, B - 70mm, C - 97.5mm, D - 24.5mm, E - 20mm, F - 63.5mm, G - 70mm
  • Weight: 0.356 Kg
Electrical Connection:
The document includes an electrical diagram for proper installation and connection of the pressure control device.
