2 INTRODUCTION
This installation, operation, and maintenance manual is designed to help you achieve the best performance
and longest life from your Summit Pump.
This pump is a positive displacement internal gear type. The pump’s drive shaft turns a ring gear (rotor), with
internal teeth, which rotates the external gear (idler). The idler rotates on a pin and meshes its external teeth
with the rotor’s internal teeth.
The crescent is integrated with the pump head and spaced between the internal teeth and external teeth. As
the gear teeth disengage at the intake port, liquid enters and is trapped in the space of each gear tooth. The
liquid is carried to the discharge port. The meshing of the two gears and the space reduction, forces the liquid
from the pump through the discharge port. Figure 2-1 below illustrates the internal gear pump design
principle.
If
there are any questions regarding this pump or its application, which are not covered in this manual, please
contact your local Summit Pump, Inc. Distributor.
For information or technical assistance on the driver service, contact the driver manufacturer’s local dealer or
representative.

4 NOMENCLATURE
On page 41 of this manual, record the nameplate data from your pump. This will assist with any maintenance
questions or pump identification in the future.
As where “sections” are stated in section 4, NOMENCLATURE, refer to Page 6 for clarification.
Summit internal gear pumps are essentially identified by Model Size (sections 1 & 2, i.e. VV40LL). The
remaining format consists of the Seal Type & Material (section 3, i.e. “PK”), Materials of Construction
(sections 4 & 5, i.e. “CC”), Additional Items (sections 6, 7 & 8, i.e. “1NS”), and finally Special to
Application (section 9, if applicable, i.e. “X”). These items together represent the complete identification of
the pump and should be stated when ordering repair parts.
4.1.1 Model Size
(“VV40LL”, Sections 1 & 2) The format consists of the pump model (section 1) and the pump size (section
2).
Section 1 specifies a specific group or style of gear pump. This value changes when the style of gear pump is
altered. For this manual section 1 is “VV40”.
Section 2 identifies a specific pump size within the gear pump model. Sizes are justified via the capacity
(GPM) of the pump. (i.e. “LL”)
4.1.2 Seal Type & Material
(“PK”, Section 3) Section 3 identifies how the pump is sealed and with what materials. Options are packing,
type 1 or type 9 component mechanical seals, or a cartridge mechanical seal.
4.1.3 Materials of Construction
(“CC”, Sections 4 & 5) Section 4 identifies the materials of the working internals and cast parts of the pump.
Each letter represents a relationship with these components. See Figure 4-1 for specific item materials of
construction.
Section 5 identifies the type of bushing used in the bracket and idler. Options are either carbon graphite or
bronze.

4.1.4 Additional Items
(“1NS”, Sections 6, 7 & 8) These sections define additional information about the options of the pump.
Section 6 identifies the sealing location, either behind the rotor or in the stuffing box.
Section 7 identifies the type of bracket and casing. There is an option to jacket these parts to induce a heat
exchanger for high temp applications.
Section 8 identifies the standard or larger shaft diameter.
4.1.5 Special to Application
(“X”, Section 9) Section 9 may or may not be present. Usually, there will be no “X” following the pump
identification. If there is an “X”, you will need to contact your nearest Summit Pump, Inc. Distributor to
determine exactly what makes this pump special.

5 RECEIPT AND STORAGE
5.1 RECEIVING THE PUMP
Immediately upon arrival, carefully inspect the pump for evidence of damage during transit. Immediately
report any damage to your local Summit Pump, Inc. Distributor.
5.2 STORING THE PUMP
5.2.1 Temporary
Temporary storage: less than six months.
1. Flush the pump with clean water. If pumped product is water reactive, remove the pump head, and
with compressed air blow all liquid from cavity. Lightly cover all internal metal parts with oil and
replace the head.
2. Store pump in a clean, dry place, free from extreme swings in temperature and humidity.
3. Cover with a protective covering to reduce dust contamination.
4. Loosen the packing gland nuts; remove the gland, packing rings and lantern ring. Apply grease to the
stuffing box I.D. and packing rings. Return the packing and lantern rings to their position in the
stuffing box. Snug down the packing gland nuts finger tight. Do not use grease if gland is water
flushed. Only a small amount of light oil should be applied in this scenario.
5. Rotate the shaft once a week to protect the bearings from being indented into the raceway.
5.2.2 Long Term
Long Term Storage: more than six months.
1. Follow temporary storage guidelines 1-5.
2. Coat all unpainted and machined surfaces with a rust inhibitor, such as LPS-3.
5.3 HANDLING
Pump unit boxes and crates may be unloaded using a forklift or slings depending on size and package
construction.
WARNING
Pump and assemblies are heavy, improper
handling could result in serious injury.
5.4 LIFTING
To avoid damage to pump and/or motor use a nylon, chain, or a wire rope sling. The slings should be placed
so lift is equally supported at four or more points.
Be sure all components are securely
fastened to baseplate before lifting.
WARNING
SUMMIT PUMP MODEL VV40 INTERNAL GEAR PUMP 7
INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
6 INSTALLATION
6.1 GENERAL
Summit Pumps are fully assembled at the factory. The pumps are ready to be installed and put into service.
Follow all instruction tags on the pump.
6.2 LOCATION
If the pump is going to have a water flush, it should be located as close as possible to the supply of water.
Other location considerations are: easy access for inspection, maintenance and ample overhead space for
lifting with crane or hoist.
6.3 BASE PLATE
Each pump unit should be mounted on a fabricated steel base plate. Common base configurations are inline,
piggyback and L-shape. The base plate should be mounted on a concrete sub base 4” to 8” longer and wider
than the fabricated base plate.
6.4 FOUNDATION
6.4.1 Concrete Sub-Base
The concrete sub foundation performs a number of functions. It must support the weight of the entire pump
assembly, maintain the alignment of all system components, and absorb the loads, forces and vibrations that
are developed under normal operating conditions. The concrete material used must be top quality and
conform to local building codes as well as the contractor’s strength requirements. Reinforcing bars and mesh
should be used as required. The mounting surface of the concrete foundation must be flat and level beneath
the footprint of the sub-base, or the pump could be installed out of square. This could create problems
aligning the piping, place extra loads on the couplings and bearings, and alter the operating levels of
lubricants or hydraulic fluids in the system. It is recommended that the top surface of the slab be held flat and
level to at least F50 according to American Concrete Institute (#117) and the Canadian Standards
Association (#A23.1) which is approximately 1/8” per 10 foot. The sub base height is usually determined by
the process piping runs and elevation.
The weight of the sub foundation should be 3-5 times the weight of the pump, motor and baseplate.
Dimensionally, it should be 4” to 8” longer and wider than the polymer concrete or fabricated steel base
plate. Anchor bolts are installed in pipe sleeves. The pipe diameter is 2.5 times larger than the anchor bolt
diameter. This sleeve/bolt assembly is embedded in the base when poured.
The pipe sleeve should be filled with sand or plastic foam to the top of the sleeve. This will prevent the grout
material from spilling into the sleeve and reducing the movement of the sleeve when pouring the grout.
Anchor bolt sizes: 1”-8UNC. Length is 7.5” to 10”, depending on base thickness and overall size.

Figure 6-2: Wooden Wedges
6.5 BASE PLATE GROUTING
1. This grouting instruction assumes a concrete sub base has been put in place to accept the baseplate.
The subbase should be clean of dirt, oil and any other debris.
2. Shims/wedges should be wood.
3. Shims/wedges should be placed on the sub base, as shown in Figure 6-3. Use 2 to 3 per stack to
obtain desired gap between baseplate and sub-base. Normal gap is 1” to 1-1/2”.
4. Carefully lower baseplate with pump and motor onto sub base over anchor bolts.
5. Level baseplate to 0.125” over length and 0.088” in over width.
6. When leveling is complete, uniformly hand tighten the anchor bolts.
