Abstract: A diesel driven pump package converts from a drag skid to a wheeled trailer. A skid assembly includes a welded base with a basin. A removeable fuel tank fits within the basin. Multiple mounting crosspieces extend over the fuel tank overlap side rails of the welded base and are bolted to the side rails via longitudinal slots. An engine bracket is mounted on a first one of the multiple mounting crosspieces to support an engine. A pump bracket is mounted on a second one of the multiple mounting crosspieces to supports a pump. A check valve support braces a check valve extending from the pump volute. The check valve support includes an adjustable arm. A trailer package removably attaches to the skid assembly to convert the skid assembly to a wheeled trailer.

Abstract: A modular skid assembly is provided for a pump driven by an electric motor. The skid assembly has a base including slats. A motor support to position the motor is configured to rest on the slats and to be bolted to the slats. A frame support to position a pump bearing frame is configured to rest on the slats and to be bolted to the slats. A volute support to support a pump volute is configured to rest on the slats and to be bolted to the slats. A lifting bail is configured to be bolted to the slats in one of multiple longitudinal positions along the base. A check valve support is configured to brace a check valve extending from the pump volute. The check valve support includes an adjustable arm that extends to put the adjustable arm in compression between the check valve and the base.

Abstract: Systems and methods described herein provide a vacuum priming system for close-coupled pumps. The vacuum priming system is mounted separately from a centrifugal pump and powered by an electric motor. An auxiliary vacuum pump pulls prime (e.g., water or another liquid) through a solenoid valve that is in turn connected to a connecting tube. At one end of the connecting tube is a screen and prime sensor. The screen filters particulates to protect the vacuum pump, and the prime sensor may detect when the centrifugal pump is primed. The vacuum priming system includes a self-contained control panel with an auto operation mode to only pull power during priming, reducing power consumption over the lifetime of the pump system and improving efficiency.
