Two Process Pump Platforms. One Manufacturing Source.
ANSI Pumps Pro supplies industrial process pumps and replacement components built around ANSI B73.1 and ISO 5199 / ISO 2858. The two platforms serve complementary project standards, installed equipment and regional requirements.
As a China-based manufacturer supplying established U.S. pump brands including Summit and PumpWorks, we combine casting development, precision machining, hydraulic engineering, material control and replacement-parts manufacturing under one supply chain. More than 150 custom molds have been developed for customer programs.
ISO 5199 and ISO 2858 Process Pump Standards
ISO 5199
Technical requirements for industrial centrifugal pumps
Provides a technical framework for mechanical design, shaft and bearing considerations, reliability, maintainability and process-industry operating requirements.
ISO 2858
Dimensional and nominal-duty standardization
Provides dimensional references for applicable end-suction centrifugal pumps, including pump size organization, nozzle relationships and shaft-centerline dimensions.
Final dimensional and hydraulic compatibility must be confirmed against the required pump model, duty point, material, flange standard and project specification.
Our ISO Process Pump Range
Our ISO program covers general process service, corrosive and abrasive duties, solids-handling service and selected replacement requirements for Sulzer pump installations.
ZA / ZE / ZF
Engineered equivalent solutions for selected industrial process and replacement applications.
MC Series
Equivalent pump solutions configured around the verified duty, materials and installation.
ZPP Series
Replacement and engineered pump solutions supported by casting, machining and material-selection capability.
SNS Series
Application-specific equivalent solutions with dimensional and hydraulic verification before production.
AHLSTAR-Equivalent Solutions by Process Duty
AC Standard Process Service
For clean and lightly contaminated liquids, viscous liquids, fibrous slurries, large-solids duties and selected gas-containing or self-priming applications.
DW Wear-Resistant Service
For corrosive, abrasive, viscous and fibrous slurries where hydraulic design and material selection determine wear life.
DN Non-Clogging Service
For sludge, long fibers, large solids and gas-containing process liquids where a wide hydraulic passage is required.
| Series | Capacity | Head | Pressure | Temperature |
|---|---|---|---|---|
| AC | Up to 11,000 m³/h / 48,400 US gpm | Up to 160 m / 525 ft | 16 / 25 bar, 230 / 360 psi | Up to 180°C / 355°F |
| DW | Up to 7,000 m³/h / 31,000 US gpm | Up to 110 m / 360 ft | 16 / 25 bar, 230 / 360 psi | Up to 180°C / 355°F |
| DN | Up to 2,000 m³/h / 8,800 US gpm | Up to 90 m / 295 ft | 16 bar / 230 psi | Up to 180°C / 355°F |
Pressure capability depends on pump size and material. Final selection must be verified against the required liquid, duty point and project specification.
Materials for Corrosive and Severe Process Service
We manufacture pump casings, impellers and selected wet-end components in conventional stainless steels and specialty alloys.
| Material | Typical positioning |
|---|---|
| WCB | Carbon steel construction for selected industrial services |
| CF8M | Cast 316 stainless steel for corrosion-resistant process service |
| CD4M | Duplex stainless alloy for chloride, corrosion and strength requirements |
| CN7M | Alloy 20-type corrosion-resistant casting |
| Hastelloy | High-corrosion-resistance applications |
| CZ100 | Specialty alloy option based on project specification |
| Titanium | Chloride, seawater and highly corrosive service |
| Zirconium | Specialty severe-corrosion applications |
Material availability, heat treatment, testing requirements and final selection must be confirmed for each project.

ISO Process Pump FAQ
What is the difference between ISO 5199 and ISO 2858?
ISO 5199 provides a technical specification framework for industrial centrifugal process pumps. ISO 2858 provides dimensional and nominal-duty references for applicable end-suction centrifugal pumps.
Do you manufacture complete pumps or only replacement parts?
We support complete ISO process pump assemblies and engineered replacement components, depending on the pump family and application.
Which Sulzer-equivalent pump families do you offer?
Our current program includes AHLSTAR-equivalent pumps and selected ZA / ZE / ZF, MC, ZPP and SNS equivalent families.
Can you provide a direct replacement for an existing Sulzer pump?
For selected models, we can evaluate a replacement solution. Compatibility must be confirmed using the existing model, duty point, dimensions, material and installation information.
What materials are available?
Available manufacturing materials include WCB, CF8M, CD4M, CN7M, Hastelloy, CZ100, Titanium and Zirconium, subject to configuration and project requirements.
Can you manufacture pumps for abrasive or solids-containing liquids?
Yes. The ISO platform includes AC general process, DW wear-resistant and DN non-clogging configurations. Final hydraulic and material selection is based on actual fluid and operating conditions.
