Page 17: Polyethylene Plastic Reservoir Tank
M-375D Description, Care and Maintenance Polyethylene Plastic Reservoir Tank (375 us. gal) Maintenance of this tank is required, but is simple. The tank should be cleaned on a regular basis by opening the drain cap on the tank tee, located at the bottom right end of the tank (see Fig.1) and rinse the tank with clear water. -
Page 18: Diesel Powered Centrifugal Pump
M-375D Description, Care and Maintenance Diesel Powered Centrifugal Pump Care and maintenance of the engine and pump are covered in this manual and/or the manufacturer operator’s manuals supplied and should be read and understood. We suggest the following daily checks be carried out prior to using the system. - Page 19 M-375D Description, Care and Maintenance Diesel Powered Centrifugal Pump Fig.4 CAUTION TRAPPED FLUID MAY BE PRESENT and will spill out when piping, hoses, pump or filter shear are removed. CAUTION NEVER LEAVE LIQUID IN THE PUMP CASING, PIPING, OR HOSES during freezing weather conditions, as damage will result.
- Page 20 M-375D Description, Care and Maintenance Diesel Powered Centrifugal Pump Grease cup instructions (Fig.5) Fill the grease cup through the grease fitting with No. 2 lithium base grease until grease escapes from the relief hole. Turn the grease cup arm counterclockwise until it is at the top of the stem; this will release the spring to apply grease to the seal.
- Page 21 M-375D Description, Care and Maintenance Diesel Powered Centrifugal Pump Grease cup instructions (Fig.5a) GREASE CUP NEEDS TO BE CLEANED REGURALY The grease cup may not perform its function properly (lubricating the seal) if it is not routinely cleaned of old hard grease build-up.

Page 22: Filter Shear System
Filter / Shear System The filter / shear (Fig.6a) system on the M-375D is an integral part of the mixing system and to operate efficiently requires daily cleaning of the stainless steel internal filter /shear. The filter / shear system is a two- piece unit (Fig.6b) consisting of an outside housing and an internal filter / shear. - Page 23 M-375D Description, Care and Maintenance Filter / Shear System continued On top of the filter / shear housing (Fig.7) are two outlets that have 1 1/2” NPT ball valves connected to them. One of the outlets (labeled) is connected to the internal jet gun inside of the reservoir tank (explained further on in this manual) and the other outlet (labeled) is to be used as a discharge for the fluid after it is mixed.

Page 24: Venturi Mixing Tee
The Venturi Mixing Tee (Fig8a.) is the very heart of this system and requires very little maintenance. However M-375D parts may wear as a result of the application in time and require replacement. This wear will become evident, when the operator notices a reduction in the vacuum that helps pull in the dry product from the hopper. -
Page 25: Wash Wand
Description, Care and Maintenance Wash Wand The M-375D is equipped with a pressurized wash wand (Fig.9a) for clearing obstructions and accumulation in the jetting tee. It is recommended that the jetting tee be cleaned with the wash wand after the introduction of material into the hopper after each batch. -
Page 26: Dry Hopper With Table & Hopper Valve
M-375D Description, Care and Maintenance Dry Hopper with Table and Hopper Valve The Dry Hopper and Table (Fig.10) are used during the initial mixing of the dry product and fluid. The hopper and table require very little daily maintenance, however care should be used that this unit does not become overloaded. -
Page 27: Internal Tank Jet Gun
M-375D Description, Care and Maintenance Internal Tank Jet Gun The Internal Jet Gun (Fig.11a) is located inside the polyethylene plastic reservoir tank, and its function is to keep the slurry product in the tank moving. This function assures the elimination of dead spots in the tank and a consistent mixture of fluid. -

Page 37: Prolonged Periods Of Storage
Prolonged Periods of Storage Prolonged Periods of Storage After a thorough cleaning of the internal and external components of the M-375D, the following steps should be applied to extend the life of your unit. • Prolonged periods of storage require extra care of the pump to protect from rusting internally. Separate the pump (as you would to replace the seal) to dry and spray with a protective oil film. -
Page 38: Optional Self-Loading Feature
Self Loading (customer to install) If the self-loading feature of The M-375D is required, you will find a 1-1/2 in. NPT (suction) port located on the venturi-mixing tee below the hopper valve (Fig.14a). All units are shipped with a plug installed in the port. -
