Usage
A submersible, self-aspirating jet aerator that is intended for aerating and mixing of

ejector system.
Pump pressure class
LT – Low head
MT – Medium head
Application limits
For temperatures higher than 40° (104°F), contact your sales and service representative.
Feature Description
Liquid temperature Maximum 40° (104°F)
pH of the pumped liquid 5.5–14
Liquid density Maximum 1100 kg/m³ (9.2 lb per US gallon)
Installation alternatives
P-installation Semi permanent, wet well arrangement with pump installed on two guide bars with
automatic connection to discharge.
The pump is installed on a discharge connection that is fixed to the base of the tank,
with the ejector system mounted on it. This installation is recommended for large jet
aerators, where moving the pump is more practical than moving the ejector system.
S-installation Portable semi permanent, wet well arrangement with hose coupling or flange for
connection to discharge pipeline.
The jet aerator is placed on the bottom of the tank. The jet aerator can be installed
without emptying the tank.
