The Wilo VeroTwin - DPL is a dry rotor double-head pump with a series structure. It is used for pumping media without abrasive materials in specific systems. It has the advantages of saving installation space, energy conservation, and corrosion resistance, and provides a variety of supporting services and documents.
- Space and Cost Saving: The double-head pump structure reduces installation space and cost.
- Diverse Operating Modes: It can be used for main/standby or peak load operation (requiring external assistance).
- Strong Corrosion Resistance: The electrophoretic coating improves the corrosion resistance standard.
- Reasonable Motor Design: The series design adopts a motor with an integral shaft, and the N model has a specific motor configuration.
- The high-efficiency hydraulic components and IE3 motor save energy.
- The structure of the cast iron parts is optimized to reduce weight.
- The production in European factories is sustainable and carbon-neutral.
It has a flange connection and includes components such as a conversion valve, mechanical seal, and a motor with an integral shaft.
It is used for pumping hot water, cold water, and water/ethylene glycol mixtures that meet the VDI 2035 standard in hot water, cold water, and cooling systems.
For example, DPL 40/160 - 4/2. "DPL" represents a pipeline double-head pump. "40" is the nominal diameter DN of the pipeline connection. "160" is the nominal impeller diameter. "4" is the nominal motor power P2 (kW). "2" is the number of poles.
