4 TPE E-circulators Speed regulation 4. Speed regulation Affinity equations WinCAPS and WebCAPS Normally, TPE pumps are used in applications characterized by a variable flow. Consequently, it is not possible to select a pump that is constantly operating at optimum efficiency. WinCAPS and WebCAPS are both selection programs offered by Grundfos. In order to achieve optimum operating economy, select the pump on the basis of the following criteria: • The max.
5 TPE E-circulators Operating conditions 5. Operating conditions Working pressure Maximum working pressure 145 psi (10 bar). Fluid temperature Maximum fluid temperature +284 °F (140 °C). Relative humidity Maximum 95%. Ambient temperature Maximum ambient temperature +104 °F (40 °C). Note: When motors installed more than 3000 ft (914 m) above sea level, the rated motor output will fall due to the low density and consequent low cooling effect of the air.

13 TPE E-circulators Installation 13. Installation Mechanical installation Elimination of noise and vibrations TP, TPE pumps can be installed in horizontal and vertical pipes. In order to achieve optimum operation and minimum noise and vibration, consider vibration dampening of the pump. TM03 3064 0206 Noise and vibration are generated by the revolutions of the motor and pump and by the flow in pipes and fittings.
13 TPE E-circulators The selection of the right vibration damper requires the following data: • forces transmitted through the damper • motor speed considering speed control, if any • required dampening in % (suggested value is 70 %). Expansion joints with limit rods can be used to reduce the effects of the expansion/contraction forces on the pipework. Anchor the pipes in such a way that they do not stress the expansion joints and the pump.
13 TPE E-circulators Carry out electrical connection and protection in accordance with local regulations. • Electronically speed-controlled pumps must always be correctly grounded. • Single-phase standard motors incorporate a thermal switch and require no additional thermal motor protection. Note: Carry out the mains connection of the pump as shown in the diagram inside the terminal box cover. Use screened cables (min. 0.5 mm2) for external on/off switch, digital input, sensor and and setpoint signals.
13 TPE E-circulators Other connections TPE See the wiring diagrams for instructions how to connect external potential-free contacts for start/stop and digital function, external setpoint signal and fault signal. Installation Note: • As a precaution, separate the wires from each other by reinforced insulation in their entire lengths. • If no external on/off switch is connected, maintain the connection across terminals 2 and 3.
