Instead of just repairing your pump, or replacing the old pump with a new pump of the same type or quality, there are other new alternative solutions for Customers.  With most pumps and pump parts coming directly, or indirectly from China and/or India, the reliability and quality of materials and parts have substantially deteriorated in the past few years forcing Customers to replace or repair products much more rapidly.

Fortunately, there are specialized engineering companies right here in the United States manufacturing machined structural engineered pumps, impellers, rings, sleeves, bearings, bushings, and mechanical seals, which are computer engineered, designed, and precision machined (not cast or molded) with the objective of  maximizing longevity and reliability.  For example, the impeller vane geometry can be engineered to maximize efficiency and performance specifically for the Customer’s system.  The best part of these alternative new solutions is that they are often very competitively priced.

Companies like SIMS in Hoboken, N.J. focus on innovative solutions for corrosion, erosion, radial thrust, and cavitation applications. They manufacture structural graphite composite computer engineered and generated replacement pumps and pump parts which are 100% machined on 5 to 8 axis robotic machining centers.

They can manufacture even obsolete parts for any centrifugal pump. SIMS focuses on life extension, which is a very different concept from traditional pump manufacturers who make their money selling spare parts.

Advance structural composite materials, like Simsite®, Never corrode in Salt Water, Waste Water, or Chlorinated water applications and are excellent for many chemical applications.  They are gradually taking market share from more traditional materials and products.

 These Impellers and Pumps are 100% machined on the inside as well as the outside from solid blocks of the structural composite, which offers Superior Mechanical Strength, Perfect Balance, Better Performance, Smoother Surfaces, and Longer Life.

Key Benefits of Using SIMSITE®Structural Composite Upgrade Solutions for Impellers, Rings, Sleeves, Guide Bearings and Pump Parts:

  • They are Corrosion resistant and Chemical resistant.
  • They NEVER CORRODE in salt water, waste water, or chlorinated water!
  • The Impellers are Cavitation & Erosion Resistant.
  • Superior to all metallic Pumps and Pump Parts in Salt Water, Waste Water and Chlorinated Water services.
  • Operate at Higher Efficiencies.
  • Lighter Weight. 15% the weight of bronze, or stainless steel. The high strength to weight ratio of the engineered composite Impeller means a substantial reduction in start-up load, longer bearing and mechanical seal life, and less shaft deflection and vibration.
  • The Impellers have Perfect Balance and they maintain this perfect balance over the life of the pump.
  • Eliminate electrolysis. These engineered structural composites are inert, which means that they do not conduct electrolysis and therefore save or prolong the life of the pump casing even if it is metallic!
  • Increase performance, longevity and reliability!
  • They are 100% precision machined from a solid block of the patented Simsite®Structural Composite, which offers Superior Mechanical Strength, Perfect Balance, Better Performance, Smoother Surfaces and Longer Life.
  • Tighter Seals.  These engineered Impellers & Casing Rings will not gall or seize like metallic rings.  Therefore, they can operate with a tighter clearance permitting less leakage through the rings and impeller which increased pump efficiency.  Additionally, the composite Casing Rings seal the casing which prevents the “wash out” of the casing ring landing areas that is a common maintenance problem with centrifugal pumps.
  • Reduces Noise and Vibration.  Because of the high efficiency and the precision machined design of the engineered Impellers, light weight, and noise absorbing characteristics of the structural engineered composite, noise & vibration are reduced in the pump.

Trouble Free Performance

Impellers machined from these alternative upgrade products such as Simsite®Structural Composite offer tremendous advantages over traditional products cast from metal – especially when the castings come from inferior casting houses.  The new Simsite®Upgrade alternative structural composite products are light weight, offer tremendous mechanical strength, and corrosion, erosion & cavitation resistance. Many of these Impellers and Casing Rings have been used successfully since 1955 in the Marine, Navy and Industrial & Chemical markets.  They have outlasted and outperformed products manufactured from bronze, stainless steel, duplex steel, monel, and even titanium.

Lower Costs – Increased Performance

The new Simsite®Structural Composite Upgrade alternative solutions for Impellers and Casing Rings are excellent for new, repair, or retrofit applications.  They are light weight and virtually indestructible.  Wear of other pump parts including the pump casing are greatly reduced because of the Impeller’s perfect balance, light weight, self-lubricating, sealing, and corrosion, erosion, & cavitation resistance.  This means far less expense for replacement of parts, downtime, and years of trouble free performance.

Designed for Superior Hydraulic Performance

Because the new Simsite®Structural Composite Upgrade alternative solution Impellers are computer engineered, designed, and precision machined, the impeller vane geometry can be engineered to maximize efficiency and performance.  Problems such as recirculation, radial thrust, and cavitation can be minimized, or eliminated by upgrading to these Impellers & Rings.  Impeller vane shapes can easily be modified to provide the best vane shape for specific applications and performance requests.


It is all too common a problem – You purchased a pump for one specific performance and when you put the pump into service in your plant, or ship, the pump operates at another point completely different from the original design point (BEP – best efficiency point) of the pump because of your system requirements.  In addition to being very inefficient, when you operate the pump away from the original design point or BEP, it causes a multitude of problems.  These problems include excessive noise & vibration, shaft oscillation, cavitation, premature wear and failure of the mechanical seals, bearings, rings, sleeves and impellers.  In extreme cases, the shaft will break.

Fortunately, these problems can be easily resolved by installing Simsite®Upgrade Solution Structural Composite Impellers & Rings which have been re-engineered for your system requirements.  Not only is the efficiency of the pump improved, but also the reliability and longevity of the complete pump is substantially improved.

Simsite® is a patented family of superior structural engineered composite Impellers, Pumps and Pump Parts offered by the SIMS PUMP VALVE COMPANY, INC. which are approved by ABS, Lloyds, and the US Navy, for Navy, Marine, Chemical, Industrial and Waste water applications.
