350-bbl Mud Premix Tanks Download Specifications

PCI Manufacturing’s Premix Mud Tank has the ability to add both dry and liquid additives through a 6” mud mixing hopper, allowing the additives to continue through three 10-HP agitators, each with a 38” impeller.

Additionally, the unit has the ability to recirculate the blended product via an MCM 8 × 6 × 14 centrifugal pump. This pumping system also allows transfer of the finished product from the pre-mix tank to production. As a value-added option, PCI’s pre-mix tank includes a completely redundant pump system to ensure continuous operation or fluid transfer in case of pump or motor failure.

Safety is a top priority for PCI in all its products. All electric controls and power cords meet Class I Division I explosion-proof specifications. Top of the tank includes foldable safety railing around the entire perimeter and open viewing area. This tank also has explosion-proof, LED lighting in both the lower pump/mixer platform and elevated over the top tank viewing area to light the interior level indicator. Removable hand rails are located above the pump/mixer platform. The mezzanine area (rated to support 100 PSF) is designed to accommodate palletized or drummed products, allowing for placement of additives not required to pass through the MCM mud mixing hopper on the lower platform. Additives may be placed onto the mezzanine with a JLG or forklift.
