Question 1

How do I choose the right DP model for my application?

Accepted Answer

Model selection is based on two key values: the required flow rate (m³/h) and head (m). The DP series covers a range from 0-22 m³/h up to 0-550 m³/h, with head up to 100 m. Share your duty point with us and we will evaluate the suitable model and its performance curve together.

Question 2

What is the difference between DB (cast body) and YB (monobloc body)?

Accepted Answer

DB (cast body) is built from modular cast components, which makes it easier to configure the number of stages to your needs and to service the pump part by part. YB (monobloc body) uses a one-piece body design that is more compact and offers higher rigidity. The DP 300 is offered in both body types; the choice depends on your installation conditions and service preferences.

Question 3

What materials are the pumps made of, and are they corrosion resistant?

Accepted Answer

On the DP series submersible pumps, the wetted parts are designed to withstand continuous submerged operation and wear. The composition of your water (chloride, sand content, pH) is the most important factor governing corrosion and wear behaviour. We recommend sharing your water analysis with us so we can evaluate together the material configuration best suited to your application.

Question 4

Are the pumps protected against dry running?

Accepted Answer

Submersible pumps rely on continuous submerged operation for cooling and lubrication; dry running can cause the motor to overheat and be damaged. We therefore recommend using a protection device in the installation, such as level electrodes or a dry-run protection relay. We can determine the appropriate protection solution together based on your application.

Question 5

How are maintenance and service handled, and are spare parts available?

Accepted Answer

DP series pumps are designed for part-by-part maintenance, and a spare-parts list is provided for each series. The maintenance interval varies with operating conditions (water quality, running hours); regular inspection extends the pump's service life. You can contact our team for service and spare-parts requests.

Question 6

Are technical documents available in different languages?

Accepted Answer

Yes. For each DP series, the general technical document and the spare-parts list are available in six languages (Turkish, English, German, French, Spanish, Russian). You can download the relevant documents in your own language from each product's detail page.

Question 7

Are the pumps covered by a warranty?

Accepted Answer

Our DP series pumps are supplied with a warranty. The warranty applies to pumps that are correctly selected and installed and operated in accordance with the catalogue values and installation instructions. Please contact us for current information on the applicable warranty period and conditions.
