Co-founded in 1992 by Don Murphy, Standard Pump is a 30-year manufacturer of hygienic and industrial process pumps, including drum pumps and other fluid handling equipment.

Both Chris Murphy and James Murphy will assume leadership roles within Unibloc, where they will utilize their expertise to support commercial and operational excellence in partnership with Unibloc leadership.

“We are thrilled to welcome Standard Pump to the Unibloc family of companies,” said Chris Stevens, CEO of Unibloc. “Standard Pump’s precision-engineered drum pumps, and hygienic pump packages position Unibloc Pump for accelerated growth. Additionally, Standard Pump’s in-house fabrication strengths, and its robust distribution network will provide new opportunities to grow sales across all flow control brands under the Unibloc banner,” added Stevens.

“As a long-time supplier to Unibloc Pump, we couldn’t be happier merging with Unibloc,” said Chris Murphy. “We’ve known and respected the company for years and have a great relationship with their team.
