Frame A/LD17 Centrifugal Pumps

The Frame A and LD17 Centrifugal Pumps are pioneering process pumps with the built-in technology to get the most from seal and bearing life. Designed around the seal where 90% of pump failures occur, these centrifugal pumps have a stiffer, heavy-duty shaft and larger bearings resulting in the widest operational window off the Best Efficiency Point (BEP) than any standard process pump. These pumps come in 11 different sizes, meaning they are applicable for a wide range of fit scenarios and application needs.

The Frame A/LD17 has the stiffest shaft in the industry, which dramatically reduces seal and shaft failures. The Frame A/LD17 reaches flow capacities of 1,400 gpm (320 m3/hr) and is available in IPP metric construction.

Features and Benefits

  • Larger bearings than competing pumps for greater load capacity and bearing life
  • Bolted retainer cover locks thrust bearing into cartridge for enhanced reliability
  • Angular contact thrust bearings
  • Low maintenance, long life, maximum value process pump
  • Most stable shaft in the industry
  • Lowest L3/D4 stiffness ratio of any competitive size pump – 17 (.65) Frame LD17
  • Dramatically reduces bearing, sealing device and shaft failures
  • Frame A meets ASME/ANSI dimensional specifications
  • LD17 configuration available for severe-duty applications
  • Capacities to 1,400 gpm (320 m3/hr)
  • Equipped to accept a C-Frame (NEMA)/D-Flange (IEC) motor adaptor, providing
    alignment of motor and power end without special tools or excessive labor
  • Right or left side discharge is possible with optional special foot
  • Heavy-duty construction and low stiffness ratios on shafts
  • Prevents common vibration damage and improves seal life
  • Short shaft overhand reduces bearing load to extend bearing life
  • Oversized heavy duty bearings provide greater load capacity and extend bearing
    life

Performance Assurance

Five Year Power End Performance Assurance

Should any Blackmer Centrifugal Power End component fail within 5 years of the original installation, including bearings or shafts that have fractured, a free replacement component will be provided. This offer is limited to a claim for one of each component per power end.*

One Year Mechanical Seal Performance Assurance

Should any factory supplied and installed mechanical seal fail within one year after the sale of the pump and seal, a spare parts kit (with materials the same as the original seal) will be provided at no charge. Limit of one seal claim per application.*

*See current Blackmer Warranty form 001-002 for full product warranty detail including exclusions and limitations of liability.

Now hear from our customers about what they had to say about Blackmer Centrifugal Pumps:

“Compared to the competition, Blackmer Centrifugal Pumps gives us the reliability and dependability we need to minimize downtime and stay competitive.”
- Jaydee Bullard, Manager of Terminals & Construction at Caljet

“It all comes down to reliability. Centrifugal pumps can operate across a wide range of their performance curve with minimal shaft deflection, which, in turn, increases mechanical seal and bearing life.”
– Anthony Paul, Director of PumpNSeal Pty. Ltd.

“The operational data of our Blackmer Centrifugal pumps proves their great reliability.”
– David Alexander, Owner of Caljet

“Blackmer offers a truly successful solution. Centrifugal Pumps deliver a truly reliable, trouble-free service.”
– Tony Ryder, Managing Director of REL

“The Centrifugal pump is perfect. We have spares, but they have been sitting on the shelf for years gathering dust because we never need them.”
– Tim Gardner, Maintenance Manager at Caljet

“From the initial engineering to the quality workmanship, Blackmer makes the perfect pump that, once put into service, will keep on running.”
– Jaydee Bullard, Manager of Terminals & Construction at Caljet
