Koehler Instrument K19201 Digital Water Washout Tester

Product Description
The Koehler K19201 Water Washout Tester for Lubricating Greases. Water Washout is a key test needed to evaluate a greases ability to act as a sealant to an ingress of water. The amount of grease that is washed out when subjected to a steady water stream is determined as per ASTM D1264, D4950 and other related specifications.
A grease sample is packed in a ball bearing and subjected to a steady water stream under controlled test conditions. The percentage of grease washed out in a one hour period is determined by weight.

Rotates a lubricated ASTM ball bearing at 600rpm in a modified bearing/housing assembly while impinging the bearing with a jet of water at the specified flow rate and temperature. The tared bearing and bearing shields are weighed before installation in the bearing housing and again after testing and drying to determine the amount of sample loss. Consists of reservoir, bearing housing, circulation system and drive motor. Reservoir is equipped with cartridge heater, thermoregulator and thermometer port for accurate temperature control at 100°F and 175°F (38°C and 79°C) per ASTM specifications. Circulation system includes constant velocity carbon bearing gear pump, valves and flowmeter directing a controlled water flow to a capillary (1mm) spray nozzle aimed at the bearing housing. Rugged 1/3hp drive motor rotates test bearing at 600rpm while driving the circulation pump. A two-pulley system permits independent pump operation to circulate water while heating it to test temperature. Mounted on a finished steel base with locating feet for permanent benchtop placement.

Drive Motor: 1/3hp 1725rpm
Temperature Control: ±1°F (±0.5°C) sensitivity
