SOLAR POWERED WATER

SOLAR POWERED WATER

Continuing from our last discussion we discussed about the LORENTZ pump and more specifically the LORENTZ PS helical rotor pumps. Today we continue with the same but on a different kind of the same pump as we seek to look at more solutions on solar water pumping.

LORENTZ PS centrifugal pumps are high quality products designed for higher flow drinking water supply, livestock watering, pond management and irrigation applications. PS centrifugal pumps provide large volumes of water economically, without pollution, anywhere.

The LORENTZ PS range of DC powered centrifugal pumps has been designed specifically to pump larger volumes of water efficiently using solar power. These highly efficient pumps can achieve flow rates of 79 m3/hour.

Each system consists of a pump, pump motor and a controller. This modular concept keeps all electronics above ground providing, simple servicing, ease of access and a low cost of ownership.

Benefits

· Long life expectancy and proven in service record

· Designed for use in remote and harsh conditions

· Smart modular design for simple and cost effective servicing and repair

· Water filled motors for reliability and to avoid oil contamination

· Fast and simple installation

· Cost effective spare parts philosophy

· Very strong ROI against diesel powered pumping reducing production costs and reducing carbon footprint

· Large range of pumps to closely match each application and optimize efficiency

Features

· Engineered in Germany

· Water temperature specific variants to provide the most efficient outputs

· High quality non corrodible materials used throughout

· Cast stainless steel components

· Solar direct connect with AC connection options

· MPPT technology to maximize power use from PV modules

· ECDRIVE DC brushless motors, designed for solar, with over 90% efficiency

· Optional data logger

IMAGINE HIGH YIELDS OF WATER WITH NO POWER COSTS

IMAGINE HIGH YIELDS OF WATER WITH NO POWER COSTS!

Water is such a precious commodity that it is actually impossible to live without it and innovation have come a long way to help us in this quest to meet our daily water demands. It is in this regard that today we shall be discussing the LORENTZ solar borehole pump and particularly the LORENTZ PS helical rotor pump.

LORENTZ PS helical rotor pumps are high quality products designed for drinking water supply, livestock watering and smaller irrigation applications. PS helical rotor pump systems deliver water economically, cleanly and reliably, anywhere.

The LORENTZ PS range of DC powered helical rotor pumps have been designed specifically to pump water efficiently using solar power. The helical rotor pump is simple, efficient and reliable, pumping water with very low levels of solar power from up to 350 m below the ground.

Each system consists of a pump, pump motor and a controller. This modular concept keeps all electronics above ground providing, simple servicing, ease of access and a low cost of ownership.

Benefits

· Long life expectancy and proven in service record

· Designed for use in remote and harsh conditions

· Smart modular design for simple and cost effective servicing and repair

· Water filled motors for reliability and to avoid oil contamination

· Fast and simple installation

DAVIS WELL PUMP

DAVIS WELL PUMP

Davis & Shirtliff Ltd has been named the leading supplier of the famous Pedrollo 4SKm well pump in East Africa and has now been rebranded as DAVIS PUMP (see picture below) The pump body & components are made of stainless steel and brass impeller now available D&S Headoffice at Nairobi Industrial area Dundori road showroom & stores, all Kenyan branches and also subsidiaries which include Tanzania, Uganda, Rwanda, Ethiopia, Zambia and South Sudan.

This new robust submersible pump is designed for pumping clean water in domestic applications from boreholes and wells and comes with 20 metres of submersible drop cable. All models feature a patented anti-seizing design to ensure that the impeller does not jam after a period of on non-operation. The compact design also includes a built-in capacitor and thermal motor overload so no separate control unit is required. It’s designed to pump a maximum head (height) of 60 metres (approx 180feet) and delivers up to 3,000 litres of water per hour

The motor is specially designed to operate continuously when fully submerged in water. You do not have to worry at all about overheating and water ingress into this motor as it’s hermetically sealed and the water down your borehole/well will act as a coolant. It’s also important to note that the pump operates on single phase power 0.75kilowatts equivalent to 1 horsepower with maximum fluid temperature of 40degree Celsius
