A local Brewery in Kentucky recently purchased Ampco’s ROLEC DH90 to safely induce hops.  Previously the brewery struggled to add hops via a scissors lift or ladder on slanted floors; now a thing of the past.  They are very pleased with unit and the benefits it has provided with quicker fermentation times and great tasting beer.


While the unit was originally designed by Ampco for safety, most brewers have found the DH90 beneficial for several other tasks.  This Kentucky brewery found the unit to be perfect not only for hops but also for inducing very thick flavorings like strawberry and blackberry purees.  Prior to the DH90 a very slow pump was used to add these flavorings into the stream of beer. The ROLEC DH-90 efficiently incorporates the flavors into the beer in less time with better flavor profiles by utilizing the chopping effect of the inline SBI Shear Blender technology.
Another advantage found by the brewery is the ability to use the unit as a simple transfer pump.  They feel they have gained a great tool and a new pump in the plant.

A poultry and meat processor was having issues with several competing PD pumps that were in service.  The processor was experiencing premature wear issues and shaft failures when pumping meat from a de-boning machine.
Ampco’s solution; a complete re-manufacture of these under-performing pumps.  Ampco replaces all internal components during remanufacturing; one piece 17-4 shafts, alloy 88 rotors, helical gears, bearings and more.
Ampco Pumps also suggested that the pumps be upgraded with a special protective coating to reduce wear from the de-boning operation.


The customer was so pleased with the performance of the first re-manufactured pump that they have sent 3 additional pumps to Ampco.  The special coating used by Ampco has greatly reduced the premature wear on the internal pump housing.

Ampco’s Patented ZP3 Series pumps were up to a recent challenge for a regional producer of personal care products.


The Corporate R&D facility was using inferior positive displacement technology during product testing. The dated technology of the competing pumps created reliability issues due to inconsistent rotor clearances making test results unreliable.
​
Ampco’s ZP Series positive displacement pumps are expertly machined utilizing a process that allows Ampco to produce ZP pumps with  rotor clearances less than .002”.

Once installed, the ZP3 pumps made consistent measurements possible and resolved the previous issues.  Learn more about the Patented ZP3 and how it is changing the positive displacement market one pump at a time.

A food processor operating multiple plants in the Midwest has made the switch.

Plant number one is familiar with Ampco’s ZP3 positive displacement pumps having several installed.  Plant number two processes a different food product and was using dated technology offered by a competing PD pump manufacturer.

Based on recommendations and successful installations at plant one and a simple presentation showing the advantages the ZP3 product provides; changes were made at plant two.

Major factors contributing to the changes are, true CIP-ablity with no loss of efficiency, significant maintenance savings due to the patented front-loading seal design, and unmatched delivery times.  Ampco delivers new PD pumps in 2 weeks or less and stocks one of the largest OEM parts inventories in the industry.  Competing brands cannot match the level of service, features and benefits offered by Ampco and the patented ZP3.
Since converting plant number two, Ampco has been successfully installing ZP Series pumps in several additional facilities domestically and abroad.
​
It’s simple; Ampco provides a superior product at a significant savings.

A few months ago a large engineering company approached us with a tricky application, which was perfect for our QTS Twin Screw Pump line.

Application: Varying types of tomato sauces and pastes with viscosities from 500 to 10000cp 7,5 m³/h and max 6 bar, partly self-priming out of barrels or small containers. Customer wanted to do the CIP duty with the same pump. (Duty 20m³/h 2 bar)

Ampco Solution: QTS 203 with 3” inlet, 2.5” outlet. Hardened casing and screws due to the abrasive media. Double mechanical seal with hard faces of SIC/SIC. Speeds from 600rpm on product to 2150 rpm on CIP.
​
Result: Engineering company and end-user were happy with on time delivery, quality and appearance of the pump and the perfectly sized application performance.
