POLY PROPYLENE MONOBLOCK PUMP
SALIENT FEATURES:-

• The volute chamber is one piece, heavy, joint less design manufactured from Poly-Propylene a chemically inert thermoplastic by the use of an exclusive moulded process.
• All the wetted parts are in solid molded
• construction to with stand corrosion and erosion.
• The impellers are semi-open type hydraulically balanced by back vanes, used in our all pumps to suit both clear & polluted fluids.
• Distance piece of pumps are made from Poly-Propylene so no corrosion problem can pump leakage.
• The bearing bracket made from heavy-duty graded casting coated with anti corrosive paint.
• Reliable fixing of impeller on the shaft by direct thread.
• Centrifugal quiet, vibration free.
• The complete pump-rotating element can be withdrawn towards the motor end without disturbing the suction or delivery pipeline, due to back pull out design.
• The motor remain fixed to base plate.
• The pump rotating element can easily be dismantled into its component. After reassemble no time consuming Re-Alignment is necessary.

• You will find maximum dimensional inter-changeability in the design of “MALHAR” Pump.
• “MALHAR” Pumps requires minimum spare parts and saves you considerable maintenance costs in the long run.
• Pumps are Available in different mounting constructions like Horizontal Bare pump , Monoblock pump and Vertical pump
• Pumps are supply with PTFE Gland Packing or Mechanical seal fitted.
• Polypropylene parts are manufactured by solid injection molding process.
• Mechanical seal are provide of Ceramic / GFT Face or Silicon face with Teflon bellow as per application.
• Gland Packing are used of PTFE Impregnated or PTFE Graphite reinforced as per application Suitable for continuous service.
• Pump casing is provide with external metal ring for construction stability.
• All non PP parts lined with anti corrosive paint to protect corrosive atmosphere

 

MATERIAL OF CONSTRUCTION & SPECIFICATIONS:-

• CASING :- Top centerline discharge and Integrated flanges , Single piece , joint less casing formed out of Injection molded polypropylene / PVDF / UHMW.
• IMPELLER :- Hydraulically balanced and accurately matched to casing profile , the semi open type impeller with particle shroud and glass finished smooth flow passage ensure high efficiency low NPSH Performance Impeller made from compressor molded polypropylene / PVDF / UHMW.
