Introduction to the VP line Marly offers a line of vertical axis pumps recently improved in hydraulic design and implemented with new models and solutions specifically developed for various industries such as firefighting equipment, petrochemical, mining plants, power plants. High efficiency, reliability, and extreme ruggedness, are the main strengths of this suite. The VP line is available with electric motor and, through the Gear Box, with combustion engine. This wide variety of versions and executions, with many materials available, makes this line of pumps extremely versatile for use in...

Main characteristics of the HP line + Thrust bearing (grease or oil with optional external cooling) for use of standard engines Axis lines with threaded or tapered joints for reliable and durable connection of the shaft Special bushings resistant to the wear of abrasive liquids and temperatures up to 180°C Control unit for electric motor, transmission angle or pulley AISI 420 stainless steel shaft for standard versions All the models in the range are available in cast iron, bronze and all kinds of stainless steel, including Duplex

Main fields of application Pumping units for fire-extinguishing equipment Geothermal water wells Water mains Petrochemical sector Agricultural irrigation Chemical systems with aggressive and/or abrasive liquids Heat treatment facilities for steel factories and/or abrasive liquids

Main technical and constructional features The impeller is available in radial or semi-axial version for maximum yield in the required working point. On the mouth it has a wearing ring that guarantees high efficiency and low wear even with abrasive liquids. To allow maintenance and disassembly ease, even after years of use, it is secured on the shaft with a tapered bushing that guarantees a perfect alignment. Axis line houses the transmission shaft on special rubber bearings to ensure optimal lubrication. To optimize its life time, the shaft is protected by a chromed steel shield. The...

Delivery drive unit is a highly important part of the pump as it houses the sealing system and the thrust bearing. Available in the version for electric motor or with gear box it has a type of bearing, grease or oil depending on the application, that can withstand axial trust up to 10,000 kg. The oil version permits external cooling of the liquid lubricant. The seals can be of packing or mechanical seal type. Drive unit A: thrust bearing B: seal system C: shaft coupling The seals can be of packing or mechanical seal type. The packing type is lubricated by the pumped liquid or externally by...
