Allweiler NT 65-200/02/199 Pump

Allweiler NT 65-200/02/199 U3.1D-W134 Centrifugal Pump – New

The Allweiler NT 65-200/02/199 U3.1D-W134 is a high efficiency horizontal volute casing centrifugal pump for demanding applications in marine, offshore and industrial fluid transfer systems. The pump is constructed to the modular ‘unit assembly’ system and DIN EN 733 requirements providing excellent dependability, efficiency and ease of maintenance in the most space constrained of engine room conditions.

Whether it’s ballast water, cooling systems or general industrial fluid movement, this genuine Allweiler device delivers the German-engineered durability needed for 24/7 vital operations.

Features and Benefits

• Marine-Grade Rugged Construction: Engineered to endure severe vibration, corrosive conditions and mechanical strain of maritime activities.
• Modular “Back Pull-Out” Design: Permits easy maintenance and examination of the rotating assembly without disconnecting the motor or the piping from the casing.
• High Hydraulic Efficiency: Special design of impeller and volute casing to ensure minimum energy consumption and operational cost.
• Versatile Fluid Compatibility: Compatible with fresh water, ocean, condensate, oils and nonaggressive industrial liquids.
• Dependable Shaft Sealing: Durable, quality mechanical seals designed for long-lasting, leak-free operation.

Where to Use?

• Shipbuilding & Offshore. Main cooling water circulation, ballast water systems, bilge pumps.
• HVAC & Thermal Management: Closed loop systems for circulation of heating and cooling fluids.
• Industrial Processing General water supply, spray-coat factories, industrial liquid transfer.
• Water Treatment: Desalination plants and water delivery.

Installation and Maintenance Guide:

1. Check Alignment. Transportation can impact alignment even when the pump and motor are pre-mounted. Check shaft alignment with a laser tool after bolting down the base plate. misplaced shaft is the #1 cause of bearing failure.
2. Monitor Suction Conditions: These pumps are prone to cavitation. Make that your suction piping is free of debris and that you have adequate NPSH (Net Positive Suction Head) margins.
3. Lubrication Schedule Bearings are good quality, however be sure to follow the lubrication type and interval indicated in the instructions. Over-greasing is just as bad as under-greasing.
4. Seal Protection The mechanical seal area needs protecting when working in dusty or sandy environments. Do not run the pump dry at any time, as this will immediately ruin the faces of the mechanical seal.
5. Vibration Analysis: Measure and record the vibration level at the bearing housing at periodic intervals. A quick rise is a definite indicator of impeller unbalance or internal wear.
