All Pratissoli high pressure pumps are of a three plunger pump design, available in 8 different ranges; each range available in different plunger diameters for a total of 41 standard models. In addition, AISI 316 . valves and heads are available for most models to suit special applications. Aluminum bronze heads are also available for the KL pump range (KLA). | PUMP CONSTRUCTION GENERAL PUMP All Pratissoli high pressure pumps are of a three plunger pump design available in 8 different ranges each range available in different plunger diameters for a total of 41 standard models. In addition AISI 316 . valves and heads are available for most models to suit special applications. Aluminum bronze heads are also available for the KL pump range KLA . Standard versions - material of construction Fluid end casting Chemical nickel-treated spheroidal cast iron Valves assembly AISI 431 . bronze spacers for KL-MS Plungers Stainless steel with ceramic coating full ceramic for VH and SH pumps . Pressure packings V-shaped double rigid rings made of special cloth and NBR rubber. Crankcase Cast iron Crankshaft up to 40 HP Forged steel hardened tempered and nitrided. above 40 HP Machined from a solid steel bar then hardened and tempered. Connecting rods Forged steel with antifriction bearings. Special versions - materials of construction The special versions are all marked with a letter after the pump name. The letter can be Z Pump head and valves are entirely made of AISI 316 . The maximum operating pressure is 1160 PSI. N Pump head made of AISI 316 . and valves made of the same AISI 431 . used for the standard versions. The operating pressure can be brought up to the standard valves. A Pump head made of aluminum bronze and valves made of AISI 316 . The maximum operating pressure cannot exceed 1160 PSI. Model EKL HD KL MS LH AISI 316 up to 1160 PSI EKLZ --- KLZ MSZ LHZ AISI 316 above 1160 PSI EKLN HDN KLN MSN LHN Aluminum bronze --- --- KLA --- --- up to 1160 PSI All A - N - Z pump versions feature marine resistant paint. Page 1 PUMP DRIVES GENERAL PUMP All pumps can be driven by means of pulleys I belts or flexible couplings. The bigger pumps MS-MH-LH-SH feature a standard gearbox available in different ratios. The other pumps are directly driven. An option flange for hydraulic drive is available for pumps up to the MS. .
