Maximize Uptime with Active Pump Monitoring
Smarter Monitoring,
Fewer Breakdowns
Sentinel’s sensor package with PLC control monitors oil pressure, filtration efficiency, performance consistency and more. Real-time diagnostics and remote monitoring deliver instant insights into critical pump parameters, allowing your team to detect issues early and take action before a breakdown occurs.
Key Benefits
Proactive maintenance alerts to prevent failures
Reduced downtime and extended pump life
Remote monitoring and real-time diagnostics
Seamless integration with existing vacuum pump systems
Sentinel Stands Guard
System Features
Lube Pressure Sensor — Detects oil pressure drops before they cause damage

Sentinel System FAQs
Have questions about the Sentinel System? As the only vacuum pump manufacturer and remanufacturer to develop an onboard monitoring system, MHV ensures seamless integration and proactive maintenance to keep your pumps running longer.
Installation is part of final assembly on an HD300 or HS430 Pump. Installation can also be purchased as an upgrade on 412H11 and 412J14 Stokes pumps (one of several MHV Uptime+ Upgrades available).
This system can digitally communicate through Ethernet connection with any client’s existing plant operation monitoring system.
Operating software is loaded into the PLC. No other software is required.
The Sentinel system is included on our MHV HD300 or HS430 Pumps. It can also be purchased as an MHV Uptime+ upgrade for any Stokes 412 remanufacture.
The oil reservoir is reworked to accommodate a multiple level liquid sensor. An oil pressure sensor is piped into the main oil supply line. A proximity sensor is mounted behind the pump flywheel that senses a puck attached to the flywheel.
