Sihi – AEH/ CEH pump

CEH
A centrifugal combined system, the CEH is self-priming and provides reliable pumping under unfavorable suction conditions. It is ideal for pumping liquids under vapor pressure, such as condensates, refrigerants and liquefied gases
+ Problem-free pumping in applications with NPSHA below 0.5 m (1.64 ft) due to centrifugal-combined system construction, which employs a centrifugal inducer stage before the side channel stages to lower NPSHR
+ Excellent hydraulic efficiency assured by modular side-channel system with one to eight stages which permits precise configuration for operating parameters
+ Low inventory carrying costs and simplified maintenance enabled by high degree of parts interchangeability between stages

AEH
The AEH is a self-priming pump designed per DIN EN 734. It is well-suited for a wide range of applications across industries, including pure, turbid or aggressive media as well as gas-entrained fluids.
+Excellent gas-handling capability due to segmental-type construction with openvane wheel impellers
+ Application versatility made possible by numerous options, including materials, bearing arrangements, sealing systems and couplings
+High-efficiency operation assured by modular side-channel system with one to eight stages, which permits precise sizing for BEP operation
+ Reduced spare parts and ease of maintenance made possible by a high degree of parts interchangeability between stages
