ANSIMax Pumps

ASME B73.1 PUMP

The advanced design of our latest ANSIMax pump significantly enhances bearing and seal life providing consistent long-term performance. All ANSIMax pumps are manufactured with quality materials in cast steel and stainless steel as standard. Optional CD4MCu and Alloy 20 optional material are available for more corrosive applications.

Hayward Gordon ANSIMax pumps are manufactured in three separate sizes with wet end designs up to 10” x 8” with a 16” impeller.  Options are based on the three available power ends and 25 different wet ends to allow a selection for the best pump to meet your process requirements.

Benefits

Hayward Gordon keeps a comprehensive inventory of ANSIMax Pumps and parts for quick turnaround times. Our in-house testing facility allows us to provide quality testing meeting customer requirements and Hydraulic Institute Standards.

Three impeller options are available for optimal matching of pump capability to application requirements:

 

  • Reverse Vane – The standard impeller design, open on back and shrouded on the front.

 

  • Semi Open Vane – Open on front and shrouded on back with pumpout vanes.

 

  • Low Flow – Specifically designed for low flow / high head applications (available in 3 different sizes, 8”, 10” & 13”).

The ANSIMax Pump can be supplied with five different seal housing covers to accommodate all sealing options. The three most popular designs are:

  • FML – Preferred design for most applications. Designed for seals with large gland bolt and gasket circles.  Oversized tapered bore with flow modifiers.  FML Seal housing is typically used with single and double cartridge seals.

 

 

 

  • CBL - Oversized, cylindrical step bore design for seals with large gland bolt and gasket circles.  CBL Seal housings are typically used with component seals.

 

 

 

 

  • CBS – Cylindrical bore design for packing arrangements and conventional seals with small gland bolt and gasket circles.

The back pull out design allows the rotating assembly to be removed without disturbing the system piping or motor.

The ANSIMax pump has been designed with versatility in mind and can handle many complex applications. Modifications can be made to allow these pumps to operate at extreme temperatures (-29°C to 260°C) using centerline mounting casings to control the thermal expansion, and can be supplied with steam jackets on both the casing and seal housings for temperature control.

 

 

 

Pumps designed to the ASME B73.1 pump standard are all dimensionally interchangeable

Industries and Applications

A Hayward Gordon ANSIMax Centrifugal Pump can be utilized for a multitude of applications in various industries.  ANSI pumps that comply with the ASME B73.1 standard, are typically used on clean fluid applications such as water or chemicals.  However, with the selection of the impeller type and material combinations, this style of pump can be used to pump corrosive fluids or fluids with minimal solids.  With the versatility of this pump, the number of pumping applications is endless.

Common ANSIMax Pumping Applications:

  • General Industry
  • Municipal – Water / Wastewater
  • Energy Oil & Gas
  • Mining

With three types of impellers available (Reverse Vane, Open and Low Flow) the ANSIMax pump can be used in countless applications and is ideal for almost any industrial process stream.  Since the ANSIMax Pump is manufactured to ASME B73.1 specifications, it is interchangeable with other ANSI pumps such as the Durco Mark IIITM.  The following are a few of the applications the ANSIMax pumps have been installed on:

  • Jet Fuel
  • Salt Brine
  • Boiler pumps
  • Oil
  • Glycol
  • Hot Water
  • Pharmaceutical / Food & Beverage
  • Breweries

Hayward Gordon ANSIMax pumps are manufactured to the current ASME B73.1 specification and are ideal for clean water applications in municipal water and wastewater plants. The pumps in these municipal applications are typically constructed of either cast steel or 316 SS. The back pull out design allows the rotating assembly to be removed without disturbing the plant piping. Impeller clearance can be set on the bench for precise clearances and renewed performance.  The following are some applications the ANSIMAX pumps have been used in Municipal plants:

  • Potable Water
  • Hot water Pumps
  • Calcium Chloride
  • Effluent Water
  • Condensate
