Your Pump’s Lifespan
How
To Increase Your Pump’s Lifespan
Sprinkler
Warehouse
Smart
Box
· A Smart Box is a combined pump start relay and pressure
sensor. In addition to connecting a pump to a 24V sprinkler timer, the Smart
Box monitors pressure on the discharge side of the pump. If the pressure within
the pump drops, the Smart Box begins a timer countdown. If the pressure has not
recovered by the end of the countdown, the Smart Box shuts the pump down.
· The countdown timer automatically resets, so when the next
pump cycle begins, if the pressure is still too low, the timer will countdown
again, allowing the pump to rebuild pressure. If the pump is able to rebuild
and maintain pressure, it will be allowed to run normally.
Start
Box
· Start
Boxes combine a pump start relay with a thermal overload
strip to protect your pump from excessive amperage draw. Drawing too many amps
will cause your pump to blow a fuse or cause heat damage to the pump itself.

Submersible
Pump Shroud
· A submersible pump shroud (or sleeve) is a casing that
goes around a submersible pump, and forces the water to flow past the pump
motor to reach the intake.
· This forced water circulation ensures adequate cooling for
the motor, increasing your pump’s lifespan by preventing the motor from
overheating.
Pump
Overheat Protection Switch (Pump Housing)
· This type of pump overheat protection switch fastens
directly to the outside of the pump housing and can be wired in one of several
ways: directly to one of the electrical supply lines (L1 or L2), directly to
the pressure switch, directly to the pump start relay, directly to the pump
station controller, or directly to the back of the motor.
Pump
Overheat Protection Switch (Pump Start Relay)
· This type of overheat protection switch fits inside pump
control boxes, and monitors for loss of suction and power fluctuations. When
abnormalities are sensed, the switch directly disconnects the pump motor.
· A recovery timer counts down to a designated time and then
reconnects the pump motor. The recovery timer can be overridden by shutting off
and then reapplying power to the switch and pump.
Recirculation
Tank
· A recirculation line prolongs your pump’s lifespan by
preventing dead-heads. Recirculation lines run from the pump discharge line
upstream of the discharge valve, back to the pump’s water source. Recirculation
lines must be sized to allow enough flow through the pump to prevent
overheating.
Cycle
Stop Valve (CSV)
· Cycle Stop Valves (CSV) increases your pump’s lifespan by
working with a pressure tank and pressure switch (or pump start relay) to
reduce your pump’s on/off cycles. The CSV mechanically controls the output flow
from your pump. For example, you would use a CSV set at 50 psi with a 40/60 psi
pressure tank.
· When the water is switched on (for household or irrigation
use), the pressure in the tank drops from 60 psi to 40 psi as the water level
in the tank decreases. Once the pressure in the tank reaches 40 psi, a signal
is sent to the pump to switch on. This is where the CSV comes in.
· When the pump starts, the CSV opens wide, to allow the
pressure tank to fill quickly. Once the pressure tank reaches 50 psi, the CSV
closes partially, and keeps the pump’s output at 50 psi. This way, the pressure
tank does not refill completely until water use at the house has stopped.
· Once the water is switched off at the house, the CSV
closes. A small amount of water is bypassed from the inlet to the outlet of the
CSV, which maintains proper cooling for the pump and slowly fills the remainder
of the pressure tank. Once the tank is full, the pump switches off.
· Without a CSV, the pump would continually cycle on and off
for the duration of the water usage at the house: while sprinklers are running,
the pressure tank would continually drop in pressure, switch the pump on,
refill to the correct pressure, switch the pump off, and begin the cycle over
again.
and homeowners needed. And it
wasn’t available. Premium prices for low-quality sprinkler materials wasn’t
cutting it. Not by a long shot. So in his garage, Steve started Sprinkler
Warehouse. Committed to providing exceptional value, amazing customer service
and premium products, Steve filled the desperate previously unaddressed need in
the irrigation supply industry.
Through building relationships
with his customers, meeting the needs of homeowners and contractors alike, and
through an unrelenting commitment to quality, Sprinkler Warehouse has grown
into a multi-million dollar company. Sprinkler Warehouse is now the largest
online retailer of sprinkler supplies in the nation and still growing. Not
content to rest in the huge success of his company, Steve Okelberry continues
to refine and innovate, bringing his customers the cutting edge in both
irrigation and customer service. No, he hasn't forgotten his roots or the
reason he began this business. It boils down to this: Best Prices, Best
Customer Service, Best Products, bar none!
