As a replacement for conventional submersible pumps, this company supplied two eight-stage, sealless canned-motor pumps of the TCAM 30/4+4 Series to a Swiss fine-chemicals company as an alternative to conventionally sealed pumps. The supplied submersible pumps (photo) are the longest pumps this company has ever produced, with an immersion depth of more than 15 m, and a pump shaft of only 1 m. The submersible pumps, in tandem design, convey the medium (ammonia) at a temperature of –33°C. The delivery head is 260 m at a flowrate of 12 m³/h. The pump units are designed for a nominal pressure of 40 bars and are suitable for operation with frequency converters (30–60 Hz). — Hermetic-Pumpen GmbH, Gundelfingen, Germany
