The company offers a range of hot water pumps for temperatures up to 530°F (277°C) and design pressures up to 1,160 psi. Due to high vapor pressures, standard mechanical seals cannot be used for higher temperatures. The easiest solution is a cooled mechanical seal, but the required cooling water has additional cost. An alternative is a standard mechanical seal with a pumping device and an external air cooler. The cooler is a recent development for this application, and it does not need cooling water. It is self-venting.
