Hydraulic Fluid and Equipment Safety
This system uses hydraulic equipment with hydraulic fluid under extremely high pressure.
Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin causing serious injury.
Keep all hoses and connections in good serviceable condition. Failure to heed may result in serious personal
injury or death. Avoid the hazard by relieving the pressure before disconnecting lines or performing work on
the system.
Make sure hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before
applying pressure to the system. Use a piece of paper or cardboard, NOT BODY PARTS, to check for sus-
pected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems.
DO NOT DELAY!
Check hydraulic hoses and fittings frequently. Loose, broken, and missing hardware can cause equipment to
not perform properly and can result in serious injury or death.
Hydraulic systems can be hot and cause burns. Before working on any system, wait until the fluid has
cooled.
If an accident occurs, see a doctor familiar with this type of injury immediately. Any fluid injected into the skin
or eyes must be treated within a few hours or gangrene may result.
A Word to the Operator
It is YOUR responsibility to read and understand the safety messages in this manual. YOU are the key to

Electromagnetic flowmeters are superior to traditional turbine flowmeters in two basic ways. First, they
have no moving parts. There are no wear items or potential for contaminants to jam a spinning turbine.
Second, electromagnetic flowmeters detect the flow by electrically measuring the velocity of the liquid,
which makes them independent of viscosity or density of the fluid measured. They are extremely accurate
using the standard calibration number. SurePoint still recommends you perform a catch test to verify the
system is properly installed and configured.
The flowmeters will accurately read higher than the rated range.
Earlier model flowmeters (meters with white labels with black text) have different calibration numbers. The flow cal
number (pulses per gallon) is printed on the serial number sticker on the side of the flowmeter.

How section valves work
Section valves can be assembled into
groups with a common inlet to control flow to each
section. Common assemblies use up to 5-6
valves, however, more can be used where
practical. Many alternate fittings can be used to
accommodate different hose sizes and
configurations.
The valves have a 3-pin weather pack
electrical connector. This has a power, ground,
and switched wire. The power measured to
ground should have 12 volts when the controller is
on. The switched wire will have 12 volts to turn
the valve on, and 0 volts to turn the valve off.

How LiquiShift Works
LiquiShift is a two-valve manifold specifically
built and controlled to provide the operator a very
wide flow range for variable rate application. It is
valuable for variable rate prescription application or
high-speed implements, or variable rate between
different fields. LiquiShift has an A and B valve that
are opened based on the system pressure.
The valves themselves are identical to a
regular section valve (KZ TX2) and have a 3-pin
weather pack electrical connector.
The A Valve is connected to a set of smaller
metering tubes. The B Valve is connected to a set of
larger metering tubes. The LiquiShift controller
automatically turns on the A valve, or the B valve, or
both valves depending on the flow required.
Gen3 LiquiShift systems on the Sentinel are
available with up to 16 sections depending on the
implement.

The Sentinel has the ability to show fertilizer system pressure on the display. The pressure
sensor is most often mounted on electric section valves when used in PumpRight systems.
The pressure sensor is a 100 psi, 0 to 5 volt 3-wire type sensor. The sensor has a 1/4” MPT fitting.
The pressure sensor is very helpful to optimize system performance and troubleshoot any issues.
See the troubleshooting section for more help.

Pump Priming and Air Bleed Valve
An air bleed valve is included with each pump to aid in system
priming. It is shipped in the pump accessories bag and must
be installed during system installation.
Why use an air bleed valve:
Most fertilizer systems are equipped with a 4 lb or 10 lb check valve on the end of each hose delivering
fertilizer to the ground. These valves do not let air escape from the system, unless it is pressurized.
PumpRight liquid pumps are not good air compressors. Therefore, the pump can struggle to prime due to air
trapped on the outlet side of the pump.
The air bleed valve is a small 1/4” valve that when opened lets air escape from the pump outlet at zero
pressure. Open until liquid comes out and then close the valve.
Be sure the air bleed valve tube does not become plugged with dirt or it will not allow air to bleed.
How to install the air bleed valve:
Remove the 1/4” plug from the quick connect fitting on the pump outlet side (see pictures below). Next, insert
the 1/4” tubing in the quick connect fitting. Run the 1/4” tubing to an easily accessible spot on your
equipment. Next, cut the tubing and push the 1/4” valve onto the tubing. Finally, run the tubing to a low
location where any fertilizer that escapes will run on the ground.
Be sure the air bleed valve tube does not become plugged with dirt or it will not allow air to bleed.

Recirculation & Agitation
A recirculation valve is standard on all 4 PumpRight models outlet
plumbing assembly.
How Recirculation Works:
When running a PumpRight pump at less than 20% of it’s maximum flow, it sometimes improves system
stability to allow the pump to run faster. Opening the recirculation valve diverts some pump flow before the
flowmeter, causing the pump to run faster. The application rate is still measured by the flowmeter and
everything that passes through the flowmeter is applied to the ground. If the pump is surging at a low flow
rate, open the recirculation regulation valve slowly until the pump runs smoothly. Start with a quarter to a half
turn. OPENING THE VALVE LOWERS THE MAXIMUM RATE THAT CAN BE APPLIED TO THE GROUND.
Close the valve if a higher rate is required.
How to modify for tank agitation:
If tank agitation is required, the recirculation valve can be re-plumbed to divert flow to the tank. All that is
required is to remove the 1/2” recirculation hose from the pump. Then replace the 3/8” MPT x 1/2” HB on the
inlet side of the pump with a 3/8” plug which is included in your PumpRight accessories bag. Finally, install a
longer 1/2” hose from the recirculation valve back to the tank.

Floating Ball Flow Indicator & Manifold System
Flow indicators give a clear visual signal that a fertilizer
system is working. These indicators use an o-ring and wire
clip connection to snap together in any configuration
necessary.
SurePoint has simple tee brackets and U-bolts that will
mount these to a variety of bar sizes.
Two main types of flow indicators are used. On 30”
row spacing, the low flow column with 1/4” push to connect
outlet is recommended for rates under 10 GPA. For rates over
10 GPA the full flow column with 3/8” hose barb outlet is
preferred.
Product Distribution
To assure proper and even distribution to each row, the product being applied
must be metered to each individual row. This metering is done by one of the 3
following methods which create back pressure so an equal amount of liquid is
applied to each row:
1. A metering orifice may be placed in the top cap of each floating ball flow indicator. (See
photos on page 12. This is not used very often.)
2. A metering orifice may be placed in the check valve cap in the line that leads to each
row. (See photo on page 14)
3. A dual metering tube kit with dual check valves may be used. (See pages 18-21)
4. A LiquiShift valve stack may be used that automatically selects which metering tube to
use based on system pressure.

The full flow column is
typically used with rates over 10
GPA on 30” rows. For rates less
than 10 GPA SurePoint
recommends the low flow columns
with 1/4” push to connect outlet
fittings.
The full flow columns are
most often assembled with 3/8”
hose barb outlets. See the low flow

Low Flow Column (mostly 1/4” QC or 3/8” QC)
The low flow column has a smaller internal diameter. This means a
heavier ball can be used to monitor a smaller flow.
SurePoint uses the low flow columns with 1/4” push to connect out-
let fittings. The flow capability of 1/4” tubing and the low flow column are a
great pair for rates on 30” rows under 10 GPA.
Externally, the low flow column can only be identified by “Low Flow”
molded into one side of the column. All the same fittings work with low flow
and full flow columns.
