Solar Powered DC Circulation Pump
Model TD5
Installation & Operating Instructions
General Information
This pump has been designed to provide versatility and
performance not available in any other high temperature DC
operated pump. It can be powered from any fixed (6V - 24V)
source or directly from a PV Solar Panel. The power level
can be manually selected or the pump can automatically
optimize power draw from a PV panel for maximum flow rate
using advanced MPPT (maximum power point tracking)
technology.
When powered from fixed sources it is suitable for a host of
applications in cars, boats, and RV's that require high
temperature and pressure capability. In Solar Water Heating
systems this pump can be connected directly to a PV panel
eliminating the need for any controllers and sensors.
Areas of Use:
• Solar Water Heating Systems
• Hot Water Circulation
• Radiant Floor Heating
• Heat Transfer Applications
• Cooling Systems
• Food Grade Liquid Transfer
• General High Temperature/Pressure Pumping
Main Features
• Selectable Power Level or full MPPT power optimization
• Brushless and Sealless, nothing to wear out
• Advanced Magnetic Drive Technology
• Durable Permanent Magnet Rotor with Ryton Impeller
• Full Stainless Steel Pump Housing
• Ceramic Shaft
• Designed for Continuous Operation, Rated for 30,000
hours
• All Food Grade Materials
• Quiet
Built-In Protective Functions
• Drive Circuitry will sense dry operation and shut down to
prevent damage
• Will slow operation or stop completely when an
overtemperature condition is detected. This can arise
due to excessive fluid temperature or excessive ambient
temperatures. The pump will automatically recover
when temperatures return to a safe level.
• Protected against overload conditions, such as can
arise if the impeller is stuck due to debris.
• Will detect overvoltage condition and shut down when
voltage exceeds 28V. Will recover automatically when
voltage falls below threshhold.
Materials
• All Wetted Parts are Food Grade
• Stainless Steel Pump Housing
• Ryton Impeller
• Viton “O” Ring
• Ceramic Ferrite Magnet
