Description

controlling of the pump system and monitoring of the operating states, Mounted at surface (no electronic parts submerged), Two control inputs for well probe (dry running protection), float or pressure switches, remote control ete, Automatic reset 20 minutes after well probe turns pump off, Protected against reverse polarity, overload and high temperature, Speed control, max. pump speed adjustable to reduce flow rate to c. 30%, Solar operation: integrated MPPT (Maximum Power Point Tracking), Battery operation: low voltage disconnect and restart after battery has recovered, Max. efficiency 92% (motor + controller), Enclosure: IP 54 (sealed, weatherproof) Motor ECDRIVE 1200HR / C, Brushless DC motor, No electronics inside motor, Water filled, IP68, pressure balanced, unlimited submersion, Dynamic slide bearings, material: carbon/ ceramic, Wetted material: stainless steel (AISI316), POM, rubber, cable drinking water approved, High life expectancy, Stainless steel none-return valve, Dry running protection, Material: stainless steel (AISI 316), rubber HR Pumps Only, Helical rotor pump (positive displacement pump), Two main parts only: stator and rotor, field serviceable, Stator: geometry made of abrasion resistant rubber, Rotor: stainless steel, hard chrome plated, abrasion resistant, More resistant to damage by sand than other pump types, Self-cleaning. PUMP The Lorentz PS-HR range are high specifications solar powered helical rotor pumps specifically designed for high head borehole applications and feature a remote surface mounted controller. Pumps are constructed principally from AISI 304/316 stainless steel and are engineered to the highest standards to give easy serviceability, excellent efficiency, high reliability and long life. MOTOR The pumps are fitted to ECDRIVE HR maintenance-free, water-filled brushless DC motors without integrated electronics. They should be powered by solar arrays configured to provide the input voltage required and sized at approx 120% of the rated motor power. Speed: 900-3300 rpm Insulation Class: F Enclosure Class: IP68 CONTROLLER Pumps are provided with matched controllers for monitoring, protecting and controlling pump operation that feature:- Protection against reverse polarity, overload and over temperature. Integrated MPPT (Maximum Power Point Tracking) for maximum solar energy conversion efficiency. Low voltage disconnect for battery protection. Control inputs for dry running protection and remote control. PUMP OUTPUTS Pump output curves are given at standard test conditions of 1000W/m2 solar irradiance and 250C. Output will vary throughout the year depending upon prevailing irradiation levels. For estimated daily outputs at continuous pumping multiply the indicated output at the duty point by the daily irradiation given in Graph 1. For indicative purposes factors of 1.1 can be applied for hot arid areas and 0.9 for temperate high altitude areas in East Africa. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2. NOTE: Output estimations are strictly indicative. More accurate projections are available using manufacturers data when the exact site location and installation arrangement is defined. This information will be provided with all offers. OPERATING CONDITIONS Pumped liquid: Thin, clean, chemically non-aggressive liquids without solids and fibres. Maximum liquid temperature: 500C Ambient Temperature: -300C- +500C Max. depth of immersion: 250m Minimum borehole diameter: 102mm
