Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions supplied with the product. Nominal capacities For full capacity details for a specific application consult Spirax Sarco. To accurately size the pump trap, the following data is required. 1. Installation head available, from the base of the pump trap to the centre line of the heat exchanger/process condensate outlet (m). If the outlet is mounted vertically, then this should be from the base of the pump to the face of the outlet.
2. Motive steam pressure available to power the pump trap (bar g) (psi g). 3. Total backpressure in the condensate return system (bar g) (psi g). 4. Heat exchanger full load operating pressure (bar g) (psi g). 5. Heat exchanger maximum steam load (kg/h) (lb/hr). 6. Minimum temperature of secondary fluid (°C) (°F). 7. Maximum controlled temperature of secondary fluid (°C) (°F).
