Centrifugal Pumps
Centrifugal pumps use rotating impellers to increase the velocity of fluids. They are commonly used to circulate fluids through a piping system. Rotina distributes centrifugal pumps from Laing, an innovative leader in spherical motor pumps. The housing and drive unit in Laing pumps are made from corrosive resistant materials such as stainless steel, plastic or titanium. Leak-proof and maintenance free, the stator is completely encapsulated. Laing pumps are designed for reliable and continuous operation.
Normal Suction Centrifugal Pumps

Laing Centrifugal Pumps
These are available in 3 material combinations of housing and drive unit:
- Plastic / stainless steel
- Plastic / titanium
- Stainless steel / Stainless steel
They have a maximum pressure of 100 kPa and max temperature of 60°C. The all stainless steel combination can endure up to 1,000 kPa and 110°C.
Self-Priming Pumps
In cases where the pump cannot be installed below the fluid level, the self-priming pump is recommended. There is no long-term interruption of the flow by air or gas pockets. Laing pumps are very reliable and often works continuously and maintenance-free for years.
Ecocirc DC Pumps
The Ecocirc® can be used wherever circulation is needed without a direct connection to AC power. Ecocirc® DC pumps can be attached directly to the DC power supply of most boiler controls due to their low power consumption. The Ecocirc series consists of D1, D2, D3 and D4 direct current wet rotor pumps which are driven by a electronically commutated stator. Applications for DC Pumps include:
- Mobile Homes (e.g. hot water heating in a mobile home, weekend home or boat)
- Ponds and aquariums
- Domestic hot water systems
- Circulating systems for industrial use (e.g. medical applications)
- Car heaters
12 Volt DC Pumps Laing DDC

DDC From Laing
The Laing DDC is the world’s first pump to be used in mass produced water-cooled workstations, and presents an ideal solution for liquid cooling of processors and electronic components. The Laing DDC has won the Innovation Award of Baden-Württemberg, Germany. Its features are as follows:
- Long & quiet service life of more than 50,000 hours
- Self-aligning pump bearing
- Maintenance-free & corrosion-resistant
