Detailed Description

AMH Series Centrifugal Pump – High Efficiency and Hygienic Design

The AMH pump is a high-performance and cost-effective centrifugal pump designed to meet the stringent requirements of hygienic applications while providing gentle product handling and excellent chemical resistance. The AMH series is available in nine different sizes: AMH-5, -10, -15, -20, -25, -30, -35, -40, and -45, offering versatile options to suit various process demands.

Standard Design

Each AMH pump is composed of a standard electric motor, pump shaft, flexible coupling (AMH-5 uses a wedge bolt), adapter, backplate, impeller, pump casing, and mechanical seal. All models are fully compatible with CIP (Clean-In-Place) systems, featuring hygienic design principles with large-radius transitions and cleanable seals to ensure optimal sanitation.

For hygienic applications, AMH pumps are equipped with a durable stainless steel motor cover that protects the motor and supports sanitary operations. Every complete AMH unit includes four adjustable stainless steel support legs for stable and flexible installation.

For industrial (non-hygienic) applications, AMH pumps are available without the stainless steel motor cover, offering a more economical solution while maintaining robust performance.

Parameter

Shaft Seal

The AMH pump is equipped with an external single mechanical seal or a water-flushed mechanical seal. The stationary seal ring is made of AISI 316L stainless steel combined with either silicon carbide or tungsten carbide, while the rotating seal ring is typically constructed from high-grade carbon (graphite). For water-flushed configurations, a durable lip seal is also included to enhance long-term performance. Additionally, the AMH pump can be optionally fitted with a double mechanical seal to meet more demanding process requirements, ensuring reliable operation under a wide range of sanitary and industrial conditions.
