 Well Probe V2
Mechanical float switch for dry run protection of LORENTZ solar pumps
The well probe provides a reliable method of run dry protection for LORENTZ pumps. The well probe
detects that water is present within a well, tank or other water source. The well probe is typically
attached to the riser pipe above the pump and connected to the controller. When the well probe
becomes dry (water level is below the probe) the pump switches off to avoid dry running.

 Liquid Level Sensor
Sensor for measuring the level of liquid in a well or tank

USE / PURPOSE
The range of liquid level sensors use pressure to measure the liquid level in a well or tank. The sensors can be used for
collection of long term liquid level monitoring and also for pump control in applications where a well probe cannot be
used. The liquid level sensor must be used with a compatible LORENTZ Controller (see requirements).

FEATURES
• Gauge pressure sensor, pressure measurement relative to atmosphere
• For measuring levels of liquid in a well or tank
• Accurate, robust sensor
• For use with LORENTZ PumpScanner and pumpMANAGER

REQUIREMENTS
• LORENTZ PS2 controller, LORENTZ PSk2 controller or PS Controller equipped
with a licensed PS DataModule
• The cable contains a capillary tube to balance the sensor against atmospheric
changes. The sensor must be ordered with the required cable length for the
application as it cannot be spliced. Further cable lengths are available on demand,
please contact LORENTZ.

 Sacrificial Anode for HR(E) Pumps
Zinc sacrificial anode for corrosion protection of HR(E) pump ends

USE / PURPOSE
The LORENTZ Sacrificial Anode is designed for use with LORENTZ pump ends. Where solar pump ends operate in aggres-
sive water conditions acidic water can attacks the passive layer of the high quality-steel pump end. This corrosion re-
duces the life time of the product. The LORENTZ Sacrificial Anode protects the pump system from this type of corrosion
and extends the pump life.

ORDER INFORMATION
• Item no.: 19-002621 Product name: Anode, Sacrificial Zink Anode, Di42mm

 Flow Sleeve for HR(E) Pumps
Device to protect the pump from dirt and for motor cooling
A flow sleeve is a sleeve that goes around the pump body and motor. It has two functions:

1. A flow sleeve reduces the amount of dirt in the pump. Where water sources contain sand or
have the potential for dirt falling into them (uncapped wells) a flow sleeve is recommended to
protect the pump from dirt. Due to the large inner diameter of the flow sleeve the water rises
very slowly and dirt deposits at the bottom of the well. Subsequently, water with less
sediments enters the pump which increases its lifetime.

2. A flow sleeve cools the motor. In open water, tanks or pools there is no natural flow of water
across the motor which can lead to heat build-up. The tube enforces water flow across the
motor which has a cooling effect.

FEATURES
• Due to the large inner diameter of the flow sleeve the water
rises very slowly allowing dirt to settle at the bottom of the well
• The life expectancy of the pump is increased due to less sand
entering the pump
• Simple installation
• Can be used with PS2-200 – PS2-4000 HR(E) Pumps
