The BP series from HRS Heat Exchangers is a purpose-designed, hydraulically-operated, reciprocating, positive-displacement pump, with an expanding cavity on the suction side and a decreasing cavity on the discharge side.
The standard series from HRS has an adjustable flow rate of between a minimum of 52 gph and a maximum of 3,170 gph, and features a high pressure drop of up to 435 psi. It is suitable for a wide range of high viscosity, shear sensitive and large particle-containing fluids. Clap valves allow pumping of whole fruits or vegetables, and an alternative piston pump with a pneumatic cylinder can be supplied for low pressure applications of less than 72 psi.
Following the success of the standard BP series in a range of applications, the company has developed three other variants for use in a range of specific situations. The first of these is the BPM series, a mobile version. This is mounted on a mobile skid unit for easy movement, allowing it to be used across multiple production lines and locations.
The second addition to the range is the BPSC Series. This has been specifically designed for highly viscous products, such as hummus, and especially those which are produced and packed at low temperatures.
The final addition is the BPH series, a horizontal version of the BP pump with a vertical inlet which has been specifically designed for products with larger sized pieces, such as fruit mixtures and coleslaw. To prevent damage to large particles, an automatic ball valve is used instead of the standard clap valve and there is also the option of a feed hopper.
