"Survivor" models increase service life and reliability.

Fennville, MI --- MHV shipped another "Survivor" model HD300 vacuum pump for a heat treating furnace built by Ipsen, going to a major heat treater in the USA.

Fennville, MI --- MHV shipped another "Survivor" model HD300 vacuum pump for a heat treating furnace built by Ipsen, going to a major heat treater in the USA.

According to Geoff Humberstone, MHV President, "The customer chose the MHV pumps for their longer life capabilities with positive pressure oil filtration in severe environments.

The HD300 provides longer life because of its robust construction and filtration that minimizes acids and contaminants that can kill other pumps." We look for future orders from heat treaters who want longer life and less downtime."

MHV "Survivor" vacuum pumps use a proven oil-sealed rotary piston design for excellent reliability even in demanding operating conditions encountered in heat treating. Their pressurized oil lubrication increases pump life significantly by using filters that clean the oil of particulates and acids. Clean oil is forced into the critical hinge bar/piston slide tang interface. The eccentric bearing bands are also pressure lubricated.

This pump design reduces the cost of ownership over the life of the pump, and helps to reduce periodic maintenance. A standard gear-type oil pump provides positive lubrication of bearings and all other moving parts. The heavy-duty roller bearing design on the main shaft extends life and gives better resistance to corrosion.

The Ipsen* furnace is designed for heat treating parts at a major commercial heat treating plant operating on multiple shifts. The customer wanted longer pump life and specified an MHV "Survivor" pump.

The Ipsen HR54X48 chamber has a hot zone which is 36 inches wide x 48 inches deep x 36 inches tall. The HD300 oil-sealed piston is the roughing pump, working with a Stokes 615 vacuum blower having a capacity of 2000 CFM (943 liters/sec). The Ipsen furnace can operate at 2400 F and 10-6 Torr with a heat exchanger for quenching.

Humberstone further comments, "We have 15 "Survivor" pumps with over 300,000 hours in operation. Their "Smart Filters" are soaking up the acids and particles that can kill standard pumps."
