Sando Pumps manufactures a range of high-quality centrifugal pumps suitable for various industrial applications. The company offers both OH1 and OH2 centrifugal pump designs, which are commonly used in the industry.

OH1 pumps are suitable for low-pressure applications and are designed with a single volute casing. OH2 pumps, on the other hand, are designed for medium to high-pressure applications and feature a double volute casing and a centerline support for the shaft.

Sando follows some of the key design standards for centrifugal pumps include:

API 610: This standard, published by the American Petroleum Institute (API), provides guidelines for the design, selection, and installation of centrifugal pumps for use in the oil, gas, and petrochemical industries. It covers various aspects of pump design, including materials, mechanical design, hydraulic design, testing, and performance requirements.
ASME B73.1: This standard, published by the American Society of Mechanical Engineers (ASME), provides specifications for horizontal end-suction centrifugal pumps used in chemical process industries. It covers requirements related to materials, mechanical design, hydraulic design, testing, and performance of the pumps.
ISO 5199: This standard, published by the International Organization for Standardization (ISO), provides guidelines for the design, performance, and testing of centrifugal pumps used in process industries. It covers requirements related to materials, mechanical design, hydraulic design, testing, and performance of the pumps.
DIN 24256 is a German standard that provides guidelines for the design, manufacturing, and performance of centrifugal pumps used in the chemical process industry. It is published by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. DIN 24256, also known as "Chemical Standardized Centrifugal Pump," covers requirements related to materials, mechanical design, hydraulic design, testing, and performance of centrifugal pumps used in chemical processes.
Hydraulic Institute Standards (HI): The Hydraulic Institute is a global authority on pumps and pumping systems, and it has published various standards related to centrifugal pumps, such as ANSI/HI 1.1-1.5 for centrifugal pump design, ANSI/HI 9.6.1 for pump testing, and ANSI/HI 12.1-12.6 for pump application guidelines.
National Electrical Manufacturers Association (NEMA) standards: NEMA publishes standards related to electric motors, which are commonly used to drive centrifugal pumps. These standards cover motor performance, electrical and mechanical design, and testing, which are important considerations in centrifugal pump design.
Local and regional standards: Depending on the country or region, there may be additional standards or regulations that govern the design and performance of centrifugal pumps, such as those related to safety, environmental protection, and energy efficiency.

Sando Pumps' centrifugal pumps are built with enduring quality and trust in mind, using high-quality materials and components to ensure reliability, durability, and efficiency. The company's centrifugal pumps are available in a range of flow rates and head ranges, making them suitable for various applications.

Overall, Sando Pumps' centrifugal pumps are an excellent choice for those looking for high-quality, reliable, and efficient pumps for their industrial applications.
