Description
Pump
| The SQF pump range comprises two pump technologies:
• the helical rotor pump (3″) for high heads and small flows. • the centrifugal pump (4″) for low heads and large flows. They are offered with stainless steel used extensively in construction for both pump designs. Pump model selection is determined by the duty requirement. |
MOTOR
| The pump is driven by a unique 1400W Grundfos MSF 3 high efficiency permanent magnet motor is specified with all pump types. The motor can be powered by either DC or AC voltage within the range of 30-300V DC and 1X90-240V, 50/60Hz AC. An integral control module uses MPPT technology that continuously optimizes output frequency to maximize system efficiency and protects against over and under voltage (except lightning), electrical overload and over temperature. Effective dry running protection is provided by a sensor in the motor cable. Maximum current is 8.4A and speed 3600rpm. |
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. |
CONTROL UNITS AND ACCESSORIES
| A variety of switch boxes are available for the various installation options including IO50 for a manual solar system, IO101 for solar/generator systems and IO102 for a wind system. In addition, a CU200 control unit is offered which provides for high-level switch control together with system monitoring and alarm indication. A complete range of accessories including connecting cabling and fittings, drop cable, module support structures are available to provide all necessary components for a complete site installation. |
SOLAR MODULES
SQ Flex systems are recommended to be powered by crystalline photo voltaic modules connected in arrays to provide the power selected.
