Vermeer adds new mud pump to its trenchless lineup

SA400 is engineered to complement the Vermeer maxi drill product line


The new Vermeer® SA400 mud pump provides a continuous flow of drilling fluid at any pump speed during drill operations. Powered by a 350-hp (261 kW) CAT Tier 4 Interim (EU Stage IIIB) engine, the SA400 joins the Vermeer lineup of maxi horizontal directional drills and reclaimers serving the pipeline installation market. 
“With the addition of the SA400, Vermeer offers pipeline contractors a one-stop shop for major components of drilling operations,” said Jon Heinen, manager for the Vermeer pipeline business segment.
The SA400 features a triplex piston pump system and has a pump capacity up to 435.3 gpm (1647.8 L/min). The pump features a clutch with a continuous duty throw-out bearing to allow extended idle while in neutral, and a suction inlet valve to suspend charged flow during drill rod makeup/breakout. The electrical centrifugal pump for the liner wash keeps the fluid end of the pump cool and lubricated. This allows the pump to run cleanly, providing a longer life for both the piston and liner.
The onboard open control station and a tethered control box allow the operator to move the control to a different location near the machine. This gives the operator the ability to monitor mud flow rate at any point around the unit, keeping an eye on pump performance wherever it is most convenient.

Jobsite efficiency is a key benefit with the SA400 mud pump. A liner wash tank is integrated into the pump design so that extra water containers or electricity are not needed for machine operation. This also allows for the pump to handle more jobsite debris.
