back pull out pump

• More than 3mm corrosion allowance (cast iron) for extended use on corrosive applications.
• Back-pull-out construction allows rotating assembly to be with drawn without disturbing the suction and delivery connections.
• one piece self vented foot mounted, center suction volute casting, single stage, closed / semi open dynamically balanced impeller.
• Flange drilling standards as per DIN 24255 / ISO 2858 or as per customer's requirement.
• Designed for 16 bar working pressure with optional casing for a working pressure of up to 20 bar.
• A robust and solid construction that guarantees long life even under high suction pressure conditions.
• Heavy-duty, deep-grooved bearings with minimum 50,000 hours operating life under normal condition. (Grease lubricated, oil lubrication available on request)
• Heavy-duty, stiff solid shaft design with low L3/D4 ratio ensures less than 0.05mm shaft deflection at the seal face in all operating condition. This extends the seal life.
• Seal housing is constructed to accommodate different seal/gland designs, so as to meet the severe heavy-duty requirements. ( standard is gland packing , seal version on special request)
• Excellent parts interchangeability reduces inventory levels for spare parts to a minimum.
• Special design for high temperature thermic fluid available in request.
• Motor or engine driven sets.
• Special monobloc versions available on request.
