Hydrostatic Test Pumps: What They Are, How They Work, and Why They MatterHydrostatic Test Pumps: What They Are, How They Work, and Why They Matter

For more than four decades, RICE Hydro, Inc. has stood at the forefront of pressure testing and utility equipment manufacturing in the United States. Founded in 1976 by Allen Rice in California, the company quickly became known for solving real-world challenges faced by contractors, municipalities, industrial facilities, and service companies — all with rugged, reliable tools built to last.

Innovation Rooted in Real Needs

The invention that started it all was the original hydrostatic test pump — a purpose-built solution for pressure testing pipelines, pressure vessels, fire suppression systems, and other pressurized lines. Prior to Rice’s design, many operators improvised with modified pressure washers, which lacked accuracy, safety, and durability. Rice’s creation changed that, offering a portable pump that delivered reliable, repeatable results with far greater precision.

A Comprehensive Product Line

Today, RICE Hydro’s product portfolio meets a wide range of industrial and construction-grade testing needs, including:

  • Hydrostatic Test Pumps – Portable and stationary units with pressure capabilities up to 30,000 PSI and flow rates up to 56 GPM. These pumps are available in gas, electric, diesel, pneumatic, and manual configurations to suit unique jobsite requirements.
  • Manual Test Pumps – Hand-operated units ideal for lower-pressure residential or small pipeline testing.
  • Fire Hose Testers – Purpose-built devices to ensure fire hose integrity in fire departments, municipalities, and service fleets.
  • Post Hole Diggers – Hydraulic and mechanical models designed for fencing, landscaping, utility, and forestry applications.
  • Shoring Pressure Pumps & Accessories – Complementary equipment that supports broader construction and safety applications.

Across all product lines, customization options including “built to suit” configurations allow customers to get exactly the performance characteristics they need.

RICE Hydro products are designed to withstand tough environments — from construction sites and rental fleets to industrial plants and military use. Their hydrostatic pumps are engineered for extended service life, often exceeding 20 years with proper maintenance, making them a cost-effective choice for long-term ownership.

Additionally, many units are designed to handle various fluids, including water, oils, chemicals, and low-level chlorine solutions, expanding their utility across diverse testing scenarios.
