Blackmer System One High Temperature Series Pump

Blackmer Centrifugal High Temperature Series

The pre-configured Blackmer Centrifugal High Temperature Series has increased the max temperature limits for Frame A and Frame M Centrifugal Pumps with the 450°F Line and 650°F Line. Now able to exceed the 400°F (204°C) standard temperature limit of Centrifugal Pumps, the High Temp Series allows for maximum temperatures of up to 450°F (232°C) with 450°F Line, 650°F (343°C) with the 650°F Line or even up to 750°F (398°C) with additional configurations and factory consultation. Utilizing high temperature flanges and elastomers, along with the unique centerline mount that supports high temperatures, the Blackmer Centrifugal High Temperature Series further entrenches these pumps ability to safely transfer critical and valuable fluids reliability in the harshest of service conditions.

High Temperature Series Advantages

Seal Chamber Jacket

Seal Chamber Jacket

A water jacketed seal chamber is available for Frame S, A, and M pumps. The jacket should be considered for any application over 350°F (177°C). When a jacket is installed, ambient temperature water at 2-3 gpm (0.45 to 0.68 m3/hr) will be required for proper cooling of the seal chamber.

Cooling Coil

Cooling Coil

Water cooling of the bearing frame is accomplished with the optional cooling coil. The cooling coil allows for oil to be cooled directly, thus cooling the bearings simultaneously. The cooling coil is required only when the pumped media temperature exceeds 400°F (204°C) at 1800 rpm or 300°F (149°C) at 3600 rpm. Under these conditions, ambient temperature water at 1-3 gpm (0.23 to 0.68 m3/hr) will be required for proper cooling of the oil.

Oil Sight Gas

Oil Sight Glass

This standard feature on all Blackmer® Centrifugal Pumps allows for easy monitor of the pump oil levels. The oil level in the bearing frame should be one-half (1/2) of the way up the oil sight glass with the unit not operating. Blackmer offers an optional second oil sight glass on the opposite side of the bearing housing for easier monitoring of the oil level.

Oil Temperature Monitor

Oil Temperature Monitor

Normal operating oil temperature should be below 160°F (71°C) and should never exceed 180°F (82°C). The optional oil temperature monitor is recommended for all applications, especially for high temperature. The device simply screws into the 1/4" NPT connection and instantly registers the temperature of the oil.

High Temperature Paint

High Temperature Paint

Blackmer Centrifugal high temperature paint is made from a specially formulated epoxy coating that will not degrade from the high temperatures within the pump. High temperature paint is recommended for pumps operating above 375°F (191°C).

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.
