Ease of installation for accurate dosing
The design of models I12, I17 and I21 is focused on achieving a small, heavy duty pump with XXL rollers that are unique on the market. The bearings installed between the rotor and the gear reducer fully absorb all the axial loads, which frees the reducer from fatigue and maximizes its service life.
Thanks to the precision of all the compression components, to the differentiated manufacturing process of the peristaltic hose, as well as the quality of its materials, a durability is achieved that is unmatched on the market.
The PeriBest Hose pump models I12, I17 and I21 cover a flow rate range between 0.02 and 4.4 GPM. These robust pumps with compact vertical design are ideal for the dosing applications for all types of abrasive, corrosive, viscous or delicate products with discharge pressures of up to 145 psi.
Dosing of chemicals, additives, lime milk, activated carbon and polymers are some of the main applications that the low flow rate PeriBest pumps solve to perfection with maximum flow rate control, process efficiency and ease of installation and maintenance.

The most compact and heavy duty solution for medium flow rates
The range of medium flow rates between 1.1 and 15.41 GPM is perfectly covered with the PeriBest pump models I28 and I35. The competitiveness of these models, both from an economic and technological point of view, positions this product range as unrivalled on the market. It is a highly efficient and heavy duty unit with a hose compression system that provides maximum accuracy, effectiveness and durability. The lack of valves and mechanical seals, the dry running capability and great suction power make the PeriBest peristaltic pump the best option for dosing or transferring highly abrasive, shear sensitive, viscous or corrosive products.
The robustness of the I28 and I35 pumps is based on the two integrated bearings, which absorb the axial loads between the rotor and the reducer, a rotor assembly and XXL rollers with maximum performance and innovative design, a compact and easy mounting system, together with very robust construction materials that are fully treated with the latest hardening and anti-corrosion processes on the market.
Like the smaller PeriBest pumps, these two models have exactly the same robustness and durability philosophy focused on a very compact, vertical design with a hose compression system using XXL rollers. This hose squeezing system with maximum surface contact, together with a differentiated and technically advanced manufacturing process of each peristaltic hose, maximises the service life of this component and reduces and optimizes maintenance and operating costs.

Transfer and dosing with maximum efficiency and durability
The I43 and I55 models complete the PeriBest peristaltic pump line with a flow rate range between 4.4 and 74.85 GPM. This can be extended by means of a double-head pump up to 149.7 GPM. These two models are perfect for dosing operations of all types of product, where, thanks to the excellent flow rate control, to the constant flow rate in variable pressure applications and to the gentle pumping, accuracies of up to ±1% can be achieved.
They are also ideal for transfer applications of fluids that are highly abrasive, viscous or contain solids in suspension, as the pump has a large solid size capacity. The lack of valves and mechanical seals, in addition to the heavy duty and horizontal monoblock design with bearing box, makes the PeriBest peristaltic pump a very robust and ideal option for any pumping application however difficult it may be. The indefinite dry running and the suction capacity of up to 31.17 ftH2O compliments the capacities of the PeriBest product range.
The installation of the bearing box in the pump casing provides perfect alignment as well as full absorption of the loads on the reducer shaft. The bearing box is made up of a central hub which supports the reinforced and oversized bearings plus the pump shaft in order to achieve a compact and very robust assembly. The incorporation of this assembly provides unbeatable robustness and strength to the pump, even in the most severe conditions with pressures up to 145 psi and in continuous working applications. Maintenance costs are minimised, system downtime is reduced and the life of the reducer is extended.
