Packo Rotary Lobe Pumps
The Packo Boa Rotorflo rotary Lobe pump is designed specifically for the food, beverage, medical and pharmaceutical industries. It is used in all hygiene-conscious process industries. The pump is EHEDG certified.
The compact BOA ROTORFLO series of pumps is designed and manufactured to international standards, with all wetted parts in 316 stainless steel.
Displacement of the BOA ROTORFLO is directly proportional to the rotational speed. The pumps fulfill the broad spectrum of process pumping duties where hygienic and non-corrosive operation is critical.
The advanced rotor profile of the BOA ROTORFLO, generated from a pure geometric form, reduces product acceleration to a minimum within the pumping chamber. This ensures a smooth, quiet, low-shear operation, combined with reduced N.P.S.H. requirement over the full performance range.
The low-shear characteristics of the BOA ROTORFLO ensure the efficient transfer of all liquid viscosities up to semi-plastic including delicate suspended solids, aggressive slurries, pastes, froths and gas/liquid mixtures without damaging the product.
Shaft Sealing
In consultation with a world-renowned seal manufacturer, a mechanical seal has been developed for the BOA ROTORFLO, which is fitted as standard to optimise cleanliness. Wide clearances on the seal particularly suit cleaning-in-place, allowing for flushing fluids to sweep the entire seal area and eliminate product and bacteria build-up. Standard seals have stainless steel and carbon faces. If required, these seals can also be supplied in tungsten carbide or silicone carbide.
Alternative gland sealing arrangements: single or double mechanical seals (with or without flushing), O-ring seals, lip seals and packed glands are available.
