Caution: Wear ear protectors!
In accordance with the laws in effect, guidelines, standards and regulations, ear protection must be worn
if the sound pressure is greater than 85 dB (A)!
The operator is responsible for ensuring that this is observed!

2.10. Pumped fluids

Each pumped fluid differs in regard to composition, corrosiveness, abrasiveness, TS content and many other
aspects. Generally, our products can be used for many applications. For more precise details, see chapter 3, the
machine data sheet and the order confirmation. It should be remembered that if the density, viscosity or the
general composition change, this can also alter many parameters of the product.
Different materials and impeller shapes are required for different pumped fluids. The more exact your
specifications on your order, the more exactly we can modify our product to meet your requirements. If the area of
application and/or the pumped fluid change, we will be happy to offer supportive advice.
When switching the product into another pumped fluid, observe the following points:

Products which have been operated in sewage or waste water must be thoroughly cleaned with
pure water or drinking water before use.

Products which have pumped fluids which are hazardous to health must always be decontaminated
before changing to a new fluid. Also clarify whether the product may be used in a different pumped
fluid.

With products which have been operated with a lubricant or cooling fluid (such as oil), this can
escape into the pumped fluid if the mechanical shaft seal is defective.
Danger - explosive fluids!
It is absolutely prohibited to pump explosive liquids (e.g. gasoline, kerosene, etc.). The products are not
designed for these liquids!

3. General description

3.1. Application

Submersion motor pumps of the TP series are used to promote sewage and wastewater as well as sludges. With
the CP series, slightly corrosive and chemically contaminated sewage and wastewater can also be promoted. A
more detailed classification according to impeller type can be found in Section 3.3.5.
The pumps are not suitable for conveying mediums with strongly abrasive components (e.g. sand, gravel,
stones).
Use in slurp mode is not permitted. The minimal level of the promoting medium must always be above the
upper edge of the pump casing, depending on the type of installation.
The temperature of the pumped medium may be up to 40°C. The maximum density of the pumped medium is
1100 kg/m³.

3.2. Types of Use

The pumps are designed for a submerged motor for operating mode S1 (continuous operation).
For a surfaced motor, the pumps are designed for operation modes S2 (short-term operation) or S3 (intermittent
operation). Please refer to the exact data in the table in Section 3.3.2 Motor.

3.3. Construction

The submersible aggregate consists of the motor, the pump casing and the suitable impeller. All important parts
are of generous dimension.
