Berkeley 4″ J Series Submersible Pumps & Liquid Ends are constructed with plastic impellers and the motor bracket and discharge are also made of extra durable poly materials like that of the Myers Rustler. So you can compare this pump or liquid end to the Myers Rustler series which we often sell as a product equal in features. Prices are comparative. We sometimes like to refer to this unit and the Myers Rustler as our economy or Chevrolet 4″ house well pump. We invite our cutsomers to visit our sister website – www.buypumpswholesale.com for pumps we are authorized to offer online to customers across the nation.
