The L8 Progressive Cavity Moyno Pump is ideal for grouting applications with neat cement and one step grouts such as Bariod Quick Grout. Two step grouts, like eight mesh Benseal, is not recommended as progressive cavity pumps over-shear the grout material and tremie lines easily plug! As a Mud Pump, the L8 Series is a popular model on many mobile pumping rigs or auger rigs in use today.

The L8 is a standard flanged pump design manufactured with cast iron or 316 stainless steel pump casings designed in 1, 2, and 3 stages for 75, 150 and 225 psi discharge pressures and a flow rate of (11.7 gallons/100 revolutions) 18 up to 100 GPM.
The L8 is a modular design with simple hardened pinned joint drive assembly. L8 Rotors are typically hardened tool steel or 316 stainless steel with a hard chrome plating for long life in abrasive pumping applications.

All other wetted parts are either carbon steel or 316 stainless steel. Stators are available in many elastomer materials such as buna, natural rubber, epdm and viton. The standard seal design is a set of gland packing with a lantern ring and flush connections. Mechanical seal options for this progressive cavity pump are readily available.

The L8 represents one of the most popular progressive cavity pumps available for the transport of drilling mud with easily replaceable in-stock parts.
