Cover
Standard seal
• The 3196 is available with a stuffing-box cover designed for a packing and a BigBore or a TaperBore
PLUS seal chamber.
Optional seal
• a dynamic seal is available which uses a repeller to pump liquid out of the stuffing box while the pump
operates. A static seal prevents leakage when the pump is shut down.
This table describes the main parts of the power end.

Condition Monitor
Description
The i-ALERT Condition Monitor is a compact, battery-operated monitoring device that continuously
measures the vibration and temperature of the pump power end. The condition monitor uses blinking red
LEDs to alert the pump operator when the pump exceeds pre-set vibration and temperature limits. This
allows the pump operator to make changes to the process or the pump before a catastrophic failure
occurs. The condition monitor is also equipped with a single green LED to indicate when it is operational
and has sufficient battery life.
Alarm mode
The condition monitor enters alarm mode when either vibration or temperature limits are exceeded over
two consecutive readings within a ten minute period. Alarm mode is indicated with two red flashing LEDs
within two second intervals.
