Pump Construction
All liquid contact parts are moulded to shape in UHMWPE - the toughest polymer with high wear & corrosion resistance.
Being a centrifugal pump, it helps in faster filling of filter press reducing cycle time.
Mechanical seal does not require an elaborate & expensive high-pressure barrier fluid system as is the case with a horizontal pump fitted with double mechanical seal for slurry handling.
Seal area is under vacuum when the pump is in running mode which prolongs seal life ; this feature enables the pump to continue running even during seal failure, So No Sudden Shutdown!
Special heavy duty thrust and self-aligning bearings take care of the large overhang due to extra vaned thrower and additional upper casing, with the mechanical seal being a unique feature of this pump. Two piece bearing housing affords a durable performance.
Shaft sleeve is made from compatible metals (Hastelloy, A-20)
Being externally mounted on a single or triple supporting frame, the pump is easily accessible for maintenance unlike a submersible pump which requires special lifting system beside having design limitation with regard to tank depth.
Pump Range : Capacity upto 300 M3/H, Head upto 10 Kg/Cm2
This unique design caters to the initial fast-filling requirement of the filtration process while ensuring automatic gradual reduction of the flow rate towards the end of filtration cycle. Unlike a horizontal pump, this vertical pump is not amenable to any damage at the end of filtration as the excess flow is fed back to the suction stream through the overflow port which acts as an in-built bye-pass system.
The mechanical seal is under slight vacuum when the pump is in operation ; this action keeps the solids-entrained fluid away from the seal faces thus increasing seal life. Even during seal failure, the pump does not suffer from any breakdown problem as the corrosive fluid does not spill out allowing filtration operation to continue unhindered.
