ANSI Process Pump — ACP Series
Centrifugal process pumps to ANSI/ASME B73.1, the dominant chemical-industry standard in North America, manufactured locally for shorter lead times than imports.

The ACP Series is a robust range of horizontal centrifugal pumps designed in strict compliance with ANSI B73.1M standards, delivering reliable performance for industrial, chemical, and pharmaceutical applications. Built through state-of-the-art investment casting, the pumps feature fully open impellers, multiple sealing options, heavy-duty bearing housings, and a modular design that ensures exceptional efficiency, easy maintenance, and maximum interchangeability of parts. Ideal for handling low-viscosity, clean, or slightly contaminated liquids, the ACP Series provides long-term reliability with superior corrosion resistance and smooth hydraulic performance.
Key features
- Investment Casting (IC)
- Fully Open Impeller
- Advanced Bearing Protection
Outcomes
- Back pull-out design and a steady supply of interchangeable spares ensure low maintenance duration.
- Centralized focus on power-efficient pumping solutions designed with higher efficiency in mind.
- Sturdy, heavy-duty bearing housings and oversized shafts with double-row thrust bearings increase service life by up to 40%.
- Capable of handling most pump duties by simply replacing bearing or shaft seal modules to meet specific requirements.
- Reduces the risk of leaks and spills caused by pump failure, protecting the surrounding environment.

How It Works
| Specification | Value |
|---|---|
| 1. Fluid Entry via Suction Nozzle | Process liquid enters through the end-suction inlet. The nozzle geometry is precision-engineered to minimise entry losses and deliver a smooth, uniform flow into the impeller eye — preventing turbulence and reducing the risk of cavitation even at high flow rates. |
| 2. Energy Transfer by the Open Impeller | The fully open impeller, manufactured via investment casting for tight tolerances, rotates at high speed and transfers kinetic energy directly to the fluid. Its open vane design handles low-viscosity and slightly contaminated fluids while reducing the risk of blockage. |
| 3. Pressure Build-Up in the Volute Casing | High-velocity fluid leaving the impeller enters the volute casing, where the expanding cross-section converts kinetic energy into pressure energy, generating discharge head up to 150 m. |
| 4. Shaft Sealing to Prevent Leakage | The rotating shaft passes through the seal chamber. Depending on configuration — mechanical seal or gland packing — the seal zone prevents process fluid escaping into the bearing housing, ensuring safe, contained operation with aggressive media. |
| 5. Discharge and Heavy-Duty Bearing Support | Pressurised fluid exits through the discharge nozzle while the heavy-duty bearing housing, with oversized shafts and double-row thrust bearings, absorbs radial and axial forces — extending service life by up to 40%. |
