The KUHLMAN INSTRUMENT COMPANY B-25 is a hand-operated pump designed for manual fluid transfer or pressure generation in field and shop applications. Hand pumps of this type are commonly used by HVAC technicians, plumbers, and service professionals who need a portable, non-powered pumping solution for tasks such as priming, testing, or fluid evacuation. The B-25 provides a straightforward mechanical operation without the need for electrical power, making it well suited for remote service calls or confined-space work where powered equipment is impractical.
The B-25 is applicable across a range of trade service scenarios including HVAC, plumbing, and general mechanical maintenance. It is intended for professional use in both residential and light commercial settings where a reliable, manually operated pump is required. The compact, portable form factor allows technicians to carry the unit in a standard tool bag for on-site use.
Designed as an OEM-style hand pump unit from Kuhlman Instrument; consult Kuhlman Instrument documentation for confirmed system or application compatibility specific to your installation.
Installation and service of hand pump equipment should be performed by a qualified trade professional. Before connecting or disconnecting the pump from any pressurized line or fluid system, relieve system pressure and shut off all upstream supply valves. Verify that all fittings and connections are rated for the intended fluid and pressure range before placing the unit into service.
