DIN 51805 Lab Lubricating Grease Flow Pressure Tester (RT-3101)
Product Details：
Low-Temperature Grease Flow Tester
Product Description
The central lubrication system typically reduces maintenance costs and increases reliability compared to traditional methods of grease application. Pressure needs to be applied to the system in order for grease to start flowing – lower temperatures typically require higher pressures than higher temperatures. This test determines the pressure required to initiate grease flow at low temperatures. The grease is injected into the test nozzle, the test temperature is reached and pressure is applied. Pressure is increased every 30 seconds until grease passes through the nozzle. Flow pressure is reported in millibars. Specify test temperature.

DIN 51805 Determination of Flow Pressure of Lubricating Greases; Kesternich Technique– need temperature
Central lubrication systems typically offer reduced maintenance costs and increased reliability over conventional grease application methods. To start the grease flowing, pressure is applied to the system – lower temperatures normally require higher pressures than higher temperatures. This test determines the pressure required to start grease flowing at low temperatures.
The grease is packed into the test nozzle, brought to the test temperature and pressure is applied. The pressure is increased in 30 second intervals until grease passes through the nozzle. Reported is the flow pressure in mbar. Please include the test temperature.
Related low temperature flow tests: Petro-lubricant Testing Laboratories offers several tests to evaluate greases for use in central lubrication systems in low-temperature environments. To empirically determine the yield stress (pressure at which the grease starts flowing), consider DIN 51805 (Kesternich Technique) or RT-3102 (Lincoln Ventmeter). To empirically determine pumpability in moving greases consider (Mobility of Greases). To evaluate apparent viscosity at varying shear rates consider ASTM D1092 (Apparent Viscosity).
