Lorentz Submersible Solar Water Pumping

The Lorentz line of submersible helical rotor and centrifugal solar water pumps can pump water from depths up to 240m.

At Center for Alternative Technologies, Nairobi, we offer design information and plans for solar and renewable energy water pumping.

There are 5 different types of the Lorentz solar water pumping systems available depending on how much water you need and from what depth.

Please click on the links to the spec sheets below for more details.

The helical rotor solar water pumps are best suited for deep well applications that require relatively low volumes of water while the centrifugal solar water pumps are best suited for shallow well applications (65’ or less) where high volumes of water are needed.

All of the Lorentz solar water pumps will fit in a 4” ID well casing or larger and require a 4-wire (3 conductor with ground) submersible cable. There is an optional low water sensor probe available which will prevent the pump from running dry as well as an AC power pack that will allow the Lorentz pumps to run off of a 120/240 VAC generator during an extended period of cloudy weather.

All Lorentz PS pumps water pumps can operate directly off of solar electric (photovoltaic or "PV ") panels, batteries or any DC power source. We are authorised distributors and installers of Lorentz submersible pumps here in Nairobi, Kenya. We offer full product information and Know how to all prospective users. Lorentz Full product warranty and support is provided by Center for Alternative Technologies.

Helical Rotor and Centrifugal Type Pumps for Solar and Battery Operation

LORENTZ PS150 C

	lift up to 22 m
	flow rate up to 5.0 m3/h
	12-24 V DC nominal voltage

LORENTZ PS200 HR/C

	lift up to 50 m
	flow rate up to 2.7 m3/h
	24-48 V DC nominal voltage

LORENTZ PS600 HR/C

	lift up to 240 m
	flow rate up to 11 m3/h
	48-72 V DC nominal voltage in solar operation
	48 V DC in battery operation

LORENTZ PS1200 HR/C

	lift up to 240 m
	flow rate up to 21 m3/h
	72-96 V DC nominal voltage in solar operation
	72-96 V DC in battery operation

PS1200 range is designed for 6-8 modules in series for a 72-96 V nominal array. This higher voltage system will allow much smaller wire sizing, decreasing system installation cost and weight. Up to 1.5 kWp can be connected

	lift up to 60 m
	flow rate up to 22 m3/h
	72-96 V DC nominal voltage

Characteristics

	high reliability and life expectancy
	helical rotor or centrifugal pump, brushless motor
	high resistance to sand and corrosion
	fits 4" and larger well casings

Application

	deep well pumping
	drinking water supply
	livestock watering
	irrigation (pressurised and non-pressurised)
	pond management
	irrigation
	etc.
