Data coverage
Liquid ring vacuum pump series pages on flowserve.com (direct): one series entry each (LPH, LPH and LEMR North America design, LEH, LEMD, Modular D / X) with the top of its published flow range ("Flows to 10350 m³/h (6090 CFM)"), kept where the CFM figure agrees
– Series pages give envelopes only; brochures show range charts, no model flow tables (the LPH 85/95 bulletin gives speeds and sound per model, no flow)
– Suction pressures and temperatures not read (no attribute for an operating suction-pressure limit)
– Dry vacuum pumps (SIHIboost, SIHIdry): pages name no mechanism ("dry-running", "electronically synchronized"); not filed. Their "< 0.1 mbar (0.7 Torr)" disagrees with itself
– Liquid ring compressors (KPH): no technology for a liquid ring compressor; not read
