Varisco J

UPRENT Ltd. October 29, 2019 0 Comment

Varisco J series are powerful self priming centrifugal pumps. Due to open type impeller these pumps are perfectly suitable for pumping of liquids that conatin large size solids, as well as for working in extreme conditions.

Operating range:

Capacity from 22 m3/h to 1400 m3/h
Suction height up to 7,5 m
Solids handling up to 76 mm

Features:

Rapid self-priming: without foot valve
Simple construction and easy inspection
High resistance to abrasive liquids
Axial mechanical seal lubricated from the outside.
Easy to install
Long life: parts subject to wear can be easily replaced

Main applications:

Industry: Transfer: clean, dirty, containing sand in suspension, muddy, neutral, alkaline, acidic liquids; low viscous petroleum products, solvents even if dirty; milk of lime, caustic soda; washing, cooling, recirculation, smoke scrubbing
Treatment: Pumping polluted, hot or corrosive waste water containing sand, mud or solids in suspension; dosing neutralising liquids; pumping out settled sludge

Naval: loading and unloading; bilge pumping; washing, fire-fighting, stripping, sanitary duty and circulation

Agriculture: Surface irrigation; liquid manure oxygenation; transfer and spraying liquid manure or fertilisers; distribution of liquid animal feed; transfer of must; washing

Civil engeneering: Drainage of excavations, canals or ponds, ground water dewatering with drains, water supply from wells or canals, washing concrete castings and aggregate, recirculation of bentonite and drilling mud

Safety: drainage after flooding or terrential rains, emergency duty: temporary sewagepumping; fire fighting; recovery of dangerous liquids

Self-priming principle

The air is drawn into the pump due to the negative pressure reated by the moving impeller and is emulsified with the liquid contained in the pump body. The air-liquid emulsion is forced into the priming chamber where the lighter air is separated and leaves through the discharge pipe; the heavier liquid drops back down into circulation.
Once all of the air has been expelled from the suction pipe, the pump is primed and works like a normal centrifugal pump. The pump can also work with an air-liquid mixture. The non-return valve has a dual function: it prevents the suction pipe from emptying when the pump is off; in the event of accidental emptying of the suction pipe, this holds a sufficient amount of liquid in the pump body to prime the pump. The discharge pipe must be free to expel the air coming from the suction pipe.

Heavy duty casing in cast iron, bronze or stainless steel. Easily opened priming, drain and impeller inspection covers.

Ductile iron, aluminium bronze or stainless steel open impeller handling large diameter spherical solids.

Externally lubricated mechanical seal. Can run dry on high vacuum even when
pumping highly abrasive liquids. Silicon or tungsten carbide seats (graphite rotating seat for versions for petroleum products). On request, double or cartridge seals.

Bearing housing with heavy duty bearings suitable for direct or V-belt drive. Standard diameter shaft extension bored and tapped to facilitate the assembly of couplings or pulleys.
