ANSI Magnetic Drive Pumps
engineered for Leak-Free Chemical Handling
Safe, sealless, low-maintenance performance for corrosive and hazardous process fluids.
Engineered or Safe Sealless Chemical Transfer
Kweng ANSI magnetic drive pumps are engineered for safe, leak-free handling of corrosive, hazardous, toxic and high-purity chemicals in demanding process industries. Built around the ANSI/ASME B73.3 dimensional standard, this range is designed for plants that require dependable sealless operation, reduced emissions, easy interchangeability and strong lifecycle performance. These pumps are especially well suited for chemical, petrochemical, pharmaceutical and speciality process applications where seal leakage, maintenance burdens and operational safety are major concerns.
Unlike conventional mechanically sealed pumps, Kweng ANSI magnetic drive pumps use a sealless magnetic coupling design that removes dynamic shaft seals and their related emission points. This helps reduce fugitive emissions, minimize seal related failures, lower maintenance frequency and improve plant safety. For buyers focused on process continuity and total cost of ownership, this means cleaner operation, less downtime and more predictable long-term performance.

ANSI B73.3 Compliance & What it Means
ANSI / ASME B73.3 is widely associated with sealless horizontal end suction centrifugal pumps used in chemical process services. For end users, compliance supports dimensional familiarity, smoother retrofit planning and better alignment with standard piping layouts. That makes ANSI magnetic drive pumps particularly attractive for plants standardized around ANSI footprints or engineering consultants who specify sealless pumps for hazardous chemical service.

FAQ
What is an ANSI magnetic drive pump?
An ANSI magnetic drive pump is a sealless centrifugal pump designed around ANSI / ASME B73.3 dimensional standards for chemical process service. It uses magnetic coupling instead of a conventional mechanical seal, helping contain the liquid within the pump and reduce leakage risks.
Why choose a sealless magnetic drive pump instead of a mechanical seal pump?
A sealless magnetic drive pump eliminates the dynamic shaft seal, which is one of the most common leakage and maintenance points in conventional pumps. This feature can reduce fugitive emissions, maintenance work, spare part usage and unexpected downtime, especially in hazardous or corrosive chemical service.
Which industries commonly use ANSI magnetic drive pumps?
These pumps are commonly used in chemical processing, petrochemical plants, pharmaceutical manufacturing, dyes and intermediates, wastewater chemical dosing, surface treatment and other industrial fluid handling applications where leak-free operation is important.
Can ANSI magnetic drive pumps handle corrosive and hazardous chemicals?
Yes. The Kweng ANSI range is positioned for handling corrosive, hazardous and high-purity chemicals, with material options such as stainless steel, duplex stainless steel, Alloy 20, Alloy C276, nickel-based materials and titanium depending on service conditions.
What is the difference between GSP and CSP series pumps?
The GSP series is intended for general service and cleaner fluid duties, while the CSP series is designed for more critical service conditions that may need additional features such as heating or cooling jackets, solids handling provisions, CIP flush, dual containment or specialized bearing arrangements.
Can these pumps be used in retrofit projects?
Yes. Because the ANSI range is designed around ANSI B73.3 dimensional standards, it is suitable for retrofit situations where users want easier replacement planning and better compatibility with existing piping layouts and plant standards.
