PERIPRO

PERIPRO peristaltic hose pumps are offered with motor power ratings from 1/4 hp to 2 hp. The smallest model, such as SKU 413GP1, uses a 1/4 hp motor and delivers a maximum flow rate of 0.48 gpm. Mid-range models like SKU 413GN7 and SKU 413GN9 use 1/2 hp motors and provide up to 1.28 gpm. Larger units, including SKU 413GM2 and SKU 413GM1, feature 2 hp motors and reach maximum flow rates of 20.5 gpm. Flow rate depends on hose diameter, motor speed, and operating pressure. For specific performance curves, refer to the individual product datasheets.

PERIPRO hose pumps are available with Buna-N, EPDM, or rubber hoses. Buna-N (nitrile) offers good resistance to oils, greases, and many hydrocarbons, making it suitable for petroleum-based fluids and some chemical dosing applications. EPDM provides excellent resistance to water, steam, ozone, and many acids and bases, but is not recommended for petroleum-based fluids. Rubber hoses are a general-purpose option for less aggressive fluids. Selection should be based on the chemical compatibility of the hose material with the fluid being pumped, as well as the operating temperature and pressure. Always verify compatibility with the chemical manufacturer's resistance data.

PERIPRO hose pumps come with several connection options to match different piping systems. Available connections include Tri-Clamp in sizes from 1/2" to 1-1/2", MNPT (male national pipe thread) in 3/4" and 1" sizes, and 1-1/2" flange connections. Tri-Clamp connections are commonly used in sanitary and food-grade applications because they allow quick disassembly for cleaning. MNPT connections are typical for industrial chemical feed lines. Flange connections are used for higher flow rates and larger hose diameters, such as the 43 mm hose models. The connection type is specified in each product's SKU description.

PERIPRO peristaltic hose pumps operate by compressing a flexible hose with rollers or shoes, which pushes fluid through the hose in a peristaltic motion. The fluid never contacts valves, seals, or impellers, so abrasive particles do not wear internal components, and shear-sensitive fluids are not damaged by high-speed mixing or impingement. This makes the pumps suitable for transferring slurries, sludges, and fluids containing solids, as well as for dosing polymers, flocculants, and other shear-sensitive chemicals. The only wetted part is the hose, which is a wear item that can be replaced periodically.

Maintenance for PERIPRO hose pumps primarily involves periodic inspection and replacement of the hose, which is the main wear component. Hose life depends on factors such as operating pressure, speed, fluid abrasiveness, and temperature. In typical chemical metering or transfer applications, hose replacement intervals may range from several months to over a year. The pump design allows hose replacement without removing the pump from the piping or dismantling the motor and gearbox. Lubricant may also require periodic checking or replacement according to the manufacturer's instructions. Always follow the specific maintenance schedule provided in the pump manual.

Yes, PERIPRO peristaltic hose pumps are capable of handling high-viscosity fluids because the positive displacement action of the hose compression can generate suction and move thick liquids. The maximum viscosity depends on the hose diameter, motor power, and operating speed. Larger hose diameters and higher motor power ratings generally allow higher viscosity. For example, the 2 hp models with 43 mm hoses (SKU 413GM2 and SKU 413GM1) are suitable for viscous slurries and pastes. However, for extremely high viscosities, consult the pump performance data or contact 3G Electric for application assistance.
