Great Plains Industries, Inc. (GPI) products

The GPI HP-100 Fluid Transfer pump is a premium fuel piston hand pump that is reliable and versatile, delivering the highest flow rate in the industry year after year. It is a single solution for multiple pumping applications, suitable for pumping fuels and motor oils. The HP-100 features a Dual-Flo^® handle providing the user with the flexibility of operating the pump at two flow rates. A setting of 1/2-gallon per stroke cycle provides faster high-capacity flow for fuels. A 1/4-gallon setting allows for easier pumping of thicker fluids, such as motor oil, even in cold temperature conditions (-25°F / -32°C).

The GPI RP-10 fluid transfer hand pump is a rotary action pump designed for direct mounting on portable tanks, drums, or barrels for the transfer of gasoline, diesel fuel, kerosene, oil (up to 30W), and hydraulic fluid. This hand pump delivers up to 10 gallons (38 Litres) per 100 revolutions. The RP-10 is the perfect pump for construction, agriculture, and other industries where maximum versatility and portability are important. 

The GPI Chemical Transfer Pump Series is engineered for dispensing, transferring, large amounts of agricultural chemicals in farming, gardening, and landscaping applications.  These pumps can be used with “thin” fluids (see viscosity specification for suitability). Portable and tank (or barrel) mount models are available.  DO NOT use with gasoline, diesel fuel, or micro-encapsulated chemicals.

The GPI LP-50 fluid transfer hand pump is a lever-action pump designed to fit tanks or 55-gallon barrels and delivers up to 1 pint (0.5 Litre) per stroke.
