Temperature
The QTS Series is designed to work in a normal temperature range between -40 °C (-40 °F) and
100 °C (212 ° F). Be careful when touching the body and gear case to avoid burns when the
temperature rises. If the application requires a higher temperature range please contact Ampco
Pumps for further information regarding the application
Moving Parts
The principal operation of the QTS Series is the rotation of a pair of synchronized rotors which can
trap foreign objects and get stuck due to improper equipment operation. Never operate the pump
without the front cover properly in place.
The gearbox contains rotating parts; never operate the pump without the gear case cover. Use
caution around rotating shaft elements. Likewise, do not operate the pump without the coupling
guard in position.
Lifting the Pump
Carefully transport the equipment avoiding contact, drops, or damage. To prevent damage, the
QTS Series is equipped with an eye bolt located on the gear case for lifting.
