Peristaltic Dispensers introduction

Peristalsis is a way of automatic contractions propelling contents along a channel or tube, this leads to a peristaltic action. By mechanical simulation of biological peristalsis, rollers crush tube walls together to form a seal while roller moves along the tube, then the previously compressed tube regains original form and sucks fluid into the formed vacuum. The fluid will follow the roller until tube is not compressed any more, then to avoid a flow back a second roller compress the tube, pushing the fluid out of the pump and repeating the suction action while the pump continues to operate the rollers which are fitted on a special rotor create suction lift and outlet pressure.

FWT (Fluid and Water Technology) offers a wide range peristaltic dispensers to satisfy most of technical requirements present in the application duties where these products are used, always keeping to offer high quality products.


 

VPER series: peristaltic dispensers with flow adjustment from 0 to 100%, enclosed into IP 65 reinforced polypropylene housing. The flow is controlled by adjusting the motor speed by means of a knob placed on the front panel.

 

UPER series: fixed constant flow rate without housing for inside mounting other equipment enclosures

 

UPER/C series: fixed constant flow rate enclosed into IP 65 reinforced polypropylene housing.

 

UPER-CD series:  peristaltic dispensers driven by an enclosed CONDUCTIVITY meter (micro Siemens) which assures a specified concentration of detergent into the basin

 

 

UPER-HF series: high flow performances, with fixed constant flow enclosed into IP 65 reinforced polypropylene housing.

 

T-VPER series: with integral TIMER (Digital or Analog settings); flow adjustment from 0 to 100%, enclosed into plastic modular housing. Recommended for applications such as dosing biological activators, odours control and hydrogen peroxide.

T-PER 12 series: powered by 12V batteries with integral TIMER (Digital or Analog settings) and fixed flow rate. Recommended for applications such as dosing biological activators and odours control, where mains are not available near grease traps.
