BEM502IRN DP : Dual pressure + Murphy gauge configuration

$2,950.00

BEM502IRN Dual Pressure
Dual pressure + Murphy gauge configuration

The BEM502IRN Dual Pump is a rugged, IP56-rated engine protection panel designed
for irrigation pumps and diesel engines where dual pump pressure monitoring is required.

Based on the proven BEM502IRN platform, this upgraded version continuously monitors critical engine
and pump conditions and automatically shuts down the engine if a dangerous fault is detected,
helping prevent costly engine damage, pump failure, and unplanned downtime.

Key monitored faults include low Pump 1 pressure, low Pump 2 pressure,
low oil pressure, high engine temperature,
alternator or belt failure, and loss of coolant water.

This model is fitted with a Murphy 20P-HL-150 high / low shutoff pressure gauge
for Pump 1, a Murphy 20P-100 low shutoff pressure gauge for Pump 2,
and a Murphy temperature gauge for dependable temperature monitoring in demanding field conditions.

The system also features a programmable start delay, tachometer input, audible alarm,
and intelligent watchdog safety logic that stores the first shutdown fault for quick diagnostics.

A reliable and cost-effective engine protection solution for irrigation and stationary diesel engine
applications requiring enhanced dual pressure shutdown capability.

Key Features

  • Dual independent pressure monitoring points
  • Murphy high / low shutdown on Pump 1
  • Murphy low shutdown on Pump 2
  • Built-in startup bypass delay
  • Fault indication and stored fault recall
  • Suitable for irrigation and stationary engine applications

Typical Applications

▶  Irrigation pump engines
