What Are Hydrostatic Test Pumps? Pressure & Flow Specs Explained

Why RICE Hydro Continues to Lead the Industry in Pressure Testing Equipment
For nearly five decades, RICE Hydro, Inc. has remained a trusted name in pressure testing and utility equipment manufacturing in the United States. Since its founding in 1976 by Allen Rice in California, the company has focused on solving practical, real-world challenges faced by contractors, municipalities, industrial facilities, and service providers. The result: rugged, dependable equipment engineered for performance and longevity.
Innovation Rooted in Real-World Experience
RICE Hydro’s legacy began with the development of the original purpose-built hydrostatic test pump. Before this innovation, many technicians relied on modified pressure washers for pressure testing—solutions that lacked precision, safety, and durability.
Allen Rice recognized the need for equipment specifically engineered for pressure testing pipelines, pressure vessels, fire suppression systems, and other pressurized infrastructure. His design introduced a portable, reliable pump capable of delivering accurate, repeatable results. That innovation established a new standard for safety and performance in the field.
