Jim Nelson’s Helpful Hints: Drum Pumps

drumYamada makes drum pumps in 3 port sizes. The 3/8” pump is available in Aluminum and Stainless Steel. The 1/2” pump is available in Polypropylene or Kynar. The 3/4” pump is available in Polypropylene, Aluminum or Stainless Steel.

All pumps come with a 2” bung fitting and fit a standard 55 gallon drum. When using a drum pump on flammable products remember to ground the barrel and the pump to eliminate state discharge.
Also, when the barrel is empty they become top heavy so make sure that it is supported properly to prevent tipping over.

Jim Nelson’s Helpful Hints: Not Your Father’s Dry Run Protector

I receive many calls from end user’s telling me that their pump has failed from dry running . Upon further investigation I find out that their problem is with a competitor’s piston pump, not an air operated double diaphragm pump.

For these applications we have suggested using our DRD-100 Dry Run Detector and have been receiving great results. So remember, dry run can be controlled on our pumps or the competition.
