The Ragazzini PSF1 is a positive displacement peristaltic [hose] pump.
An elastomeric tube is squeezed
along its length by rollers that push the fluid contained within it. It has a
“roller on bearings” design so that the pump housing does not need to be filled
with lubrication fluid. It is self priming, seal-less, can run dry without
damage, and apart from the flanges, only one part comes in contact with the
The PSF1 is self priming and
widely used in water and waste water treatment, the food and beverage industry,
chemical industry as well as construction, paper, ceramic, paints, inks, mining
and marine industries.
Ragazzini hose pumps are
available with a wide variety of hose options to suit abrasive and/or corrosive
applications and are also available with food grade hoses capable of being
sterilized with hot water [to 70o] and/or steam [to 120o].
A leak detector is standard equipment to provide early indication of hose
failure. This is a float type sensor that is located at the lowest point in the
pump. Because the pump casing is not filled with lubricating fluid and the
speed of the leak detector, contamination is and product loss is greatly
The Ragazzini PSF1 is the
perfect pump for clean in place [CIP] or sanitise in place [SIP] applications
when fitted with the optional “retractable roller”. With this system, one of
the rollers can be retracted via an over-centre rapid release cam and lever
system. This now enables full flow of a flushing/cleaning/sanitising fluid
through the hose. This new positioning system is essential for fully automated
foodstuff handling applications that require regular cleaning and sterilisation
of all the components in contact with the product.
The PSF1 can deliver up to 50
litres per minute [lpm] on intermittent applications or up to 8 lpm for heavy
duty 24/7 operations. Pressures to 15 bar can be achieved and solid particles
up to 13mm diameter can be passed through the pump. It can also be run in
reverse, making it ideal for tank emptying and filling operations. Within the
full Ragazzini range, flows as low as 0.2 litres per hour [lph] can be achieved
as well as flows as high as 180,000 lph.
