Description
KSB Ansichem Pump
The KSB Ansichem pump series delivers a robust, ANSI-compliant centrifugal pumping solution engineered for demanding chemical process applications. Designed in accordance with the ANSI/ASME B73.1 standard for horizontal, end-suction centrifugal chemical process pumps, Ansichem combines exceptional reliability, dimensional interchangeability, and service-friendly construction to meet the needs of modern process industries.
Designed for corrosive liquids, solvents, acids, and other demanding process fluids, KSB Ansichem pumps ensure dependable fluid transfer with optimized hydraulic design and adaptable materials of construction.
Key Features
ANSI Standard Compliance
-
ANSI B73.1 design ensures standardized dimensions, mounting arrangements, suction/discharge flange locations, and shaft interfaces to support interchangeability with comparable ANSI pumps from other manufacturers — simplifying replacements and upgrades.
Reliable Centrifugal Performance
-
Single-stage, horizontal, end-suction design with robust volute casing and optimized hydraulic profile for smooth flow, reliable operation, and efficient energy use under varying process conditions.
Service-Friendly Construction
-
Back pull-out design enables removal of the rotating assembly (shaft, impeller, seals, bearings) without disconnecting suction/discharge piping — reducing downtime and maintenance costs.
Material Flexibility
-
Available in a broad range of metallic materials (e.g., stainless grades, high-nickel alloys, duplex) to match chemical compatibility requirements and extend service life in corrosive environments.
Seal Options
-
Supports various mechanical seal configurations and seal support systems suitable for process liquids, offering enhanced leak control and reliability in critical chemical duties.
Ease of Integration
-
ANSI standardization ensures compatibility with industry-standard piping and baseplates, easing retrofit or system expansions.
