If you think your operations are experiencing issues or inefficiencies (or if your Quiz score indicated that you may have issues), you may be facing one of the common problems outlined below. This page is designed to help you identify early warning signs and take the right steps to prevent costly equipment failures.

Before we begin troubleshooting your system, it is important to understand the type of lubrication system you are using. Below are the most typical systems used across industries. Each illustration includes a brief description of system operation to assist with troubleshooting.

These examples show basic system functionality but remember there are many accessories available to complement these systems, including system controllers, pressure and flow monitoring devices, gauges, pressure relief devices, rigid tubing and piping, flexible connectors, visual indicators, metering devices, strainers, filtration units, and wireless feedback systems.

Common Industrial Lubrication System Types

Single Line, Series Progressive System with Fixed Output Divider Valves

This system consists of an independent pumping unit that feeds volumetric distributors equipped with several outlets. Lubricant dispensing occurs through a progressive sequence, and each outlet depends on the others. If one outlet fails or becomes blocked, the entire system will stop.

Single Line, Parallel Injector System with Adjustable Output Injectors

This system features an independent pumping unit that delivers lubricant through a single main line to independent volumetric measuring devices (injectors). Injectors operate in two phases: pressurization for lubricant delivery and depressurization for chamber reloading. Each injector can be adjusted to deliver a predetermined volume of lubricant.

Dual Line, Parallel System with Adjustable Output Blocks

This system uses an independent pumping unit feeding two separate lines alternately. Adjustable volumetric distributors are connected to both lines to dispense predefined lubricant quantities. This design provides greater reliability for larger systems.

Multiple Outlet Pumping Units

This setup includes an electric central pumping station fitted radially with independent pumping elements (up to 16). A cam-driven mechanism pushes lubricant successively to different delivery points, offering continuous system operation.

Frequently Asked Questions

Why is my lubrication system not delivering grease or oil consistently?

Possible causes:

Air locks trapped in the system
Blocked lines or fittings
Bypassing injectors due to seal failure
Pump malfunction or power supply failure
Incorrect system pressure or flow rate

What to do:

Check for obstructions or leaks, verify system pressure, and inspect the pump and dispensing injectors for signs of wear. If the problem persists, contact Forward Venture Industries for a remote diagnostic or on-site inspection.

What causes my Digital No-Flow Timer (DNFT) to trigger alarms frequently?

Possible causes:

Intermittent flow caused by partial blockages
Incorrect calibration or timer setting
Worn components in the lubrication circuit
Faulty proximity switch or sensor wiring
What to do:
Review the DNFT settings and confirm proper sensor alignment. Persistent alarms may require recalibration or replacement of outdated components.

My proximity switch is not registering lubricant flow. What should I check?

Possible causes:

Sensor misalignment Debris on the sensor face
Electrical connection failure
Flow rate too low for detection threshold
What to do:
Clean the sensor face, inspect wiring connections, and ensure correct sensor placement. If issues continue, test with known flow conditions to rule out sensor failure.

How can I tell if a lubrication pump is failing?

Warning signs:

Inconsistent pressure
Unusual noise or vibration
Oil or grease leakage around the pump
Alarms or faults triggered on system monitors
What to do:
Inspect seals and fittings, check voltage and motor function, and compare current flow readings to baseline values. Pumps showing signs of wear should be serviced or replaced promptly.

What are signs of over-lubrication?

Common indicators:

Grease or oil dripping from seals or fittings
Excessive buildup around bearing housings
Shortened bearing life or overheating
What to do:
Evaluate lubrication intervals and quantity. Automated systems can help deliver precise amounts to prevent waste and protect equipment.

What causes under-lubrication?

Common causes:

Blocked or restricted lines
Incorrect pump output settings
Failed injectors or metering devices Injector fails to reload due to inadequate resting pressure venting
Missed maintenance schedules
What to do:
Check each delivery point for flow and verify injector condition. Even if system pressure is sufficient to dispense, failure to vent resting pressure can prevent injector reloading. This fault may not trigger system alarms. Confirm that system outputs meet the specific requirements of your equipment.

Are any DNFT models becoming obsolete?

Yes. The following DNFT part numbers became obsolete at the end of 2024: 000149, 000353, 000360, and 000518. Replacement models are available with improved features and compatibility.

What to do:

If you are currently using any of these models, contact our experts to review replacement options and schedule proactive upgrades during your next maintenance window.

What can I do to prevent future lubrication issues?

Best practices:

Implement automated lubrication where possible
Use proximity switches and DNFTs to monitor real-time lubricant flow
Schedule regular system inspections and replace aging components Install proper strainers and filtration systems to maintain lubricant purity
Follow manufacturer guidelines for pump settings, grease types, and maintenance intervals
