Product Features3


Base

Series DP reels utilize two interlocking plates

stamped from 11 gauge carbon steel. They are held

permanently in place by rivets.


Spool

Next, the disc is placed. The disc is stamped

from 16 gauge steel and features 6 threaded

press studs used for bolting on the spring case.

High density poly ethylene main hub is at the

center of the spool assembly and rotates

around the main shaft when the reel is in

motion.

The flange/sheave is placed over the main hub.

The hat is stamped from 16 gauge steel and

features a partially spun outer edge.

The entire spool assembly is then

riveted together permanently. This

assembly will need to be replaced in its

entirety should any one part be

damaged.***

Steel parts are individually powder

coated for superior corrosion resistance.

***For larger models holding

longer lengths of hose a high

density polyethylene spool spacer

is added. The whole assembly is

bolted together instead of riveted.

In this instance the spool

assembly CAN be disassembled.


Main Shaft & AL Hub (Drive Side)

Main shaft

machined from

solid and

chromium free

zinc plated for

corrosion

resistance.

The main shaft is inserted into the drive side aluminum hub (pictured right). A set

screw receives thread locker and is tightened down to the small machined flat on

the main shaft. The retaining ring is then put into place. The large machined flat on

the main shaft will eventually engage the arbor key. The assembly receives a small

application of assembly lube before being inserted into the spool assembly.


Spring Case

Drive spring anchor point

Spring case stamped from 18 gauge

steel. Cast aluminum ratchet is

staked to spring case permanently to

form spring case and ratchet

assembly. Must be replaced as an

assembly if damaged.

Aluminum ratchet wheel

Bronze bushing


Spring Case

The aluminum arbor is placed over the main shaft is

placed over the main shaft and locked into place with

an aluminum key. The spring anchor is inserted into

the hole in the spring case. A small amount of lithium

based assembly lube is added to the spring case and

the drive spring is put into place.

and held in place with arbor.


Low Pressure Swivel Assembly

The swivel is threaded into the main shaft.

The addition of elbows helps to make a

better hose transition onto the spool. Teflon

tape is added to the threaded connections

between swivel/union, union/union and

union/hose.

Type: Balanced

Pressure: 500 PSI

Seals: AFLAS

Swivel side

aluminum hub

does not require

a bushing and is

held in place with

a set screw.


Medium & High Pressure Swivel Assembly

Type: Ball bearing

Pressure: 5000 PSI

Seals: AFLAS

Swivel side aluminum hub

features a bronze bushing and is

held in place with a snap ring.

The swivel spins in the arbor and

necessitates a bushing.


Aluminum Hubs

The second (and final) arbor

is placed onto the main

shaft.

The entire

assembly is then

cradled my the

base and upright.

The reel is now ready

to receive guide arms

and a roller assembly.

There are two different

swivel side aluminum

hubs. The swivel dictates

which one is used.


Guide Arm

Guide arm mounting

holes allow for guide to

be re-positioned every 45°.

Series DP reels are supported on both sides of the reel

with a guide arm stamped from industrial grade 11 gauge

steel.

Guide arms are stamped rather

than pressed, allowing us to

engineer far greater strength &

rigidity into raw steel.

Unless otherwise specified,

reels ship in the side wind

position. Reels can be

ordered in any position by

adding the correct suffix to

the part number (TW or

BW). NOTE: when a

customer changes the guide

arm position, they must

change the U-bolt location,

consult the users manual for

more information.


Ratchet & Latch Parts

Torsion springs outlast the more

conventional tension springs 10:1

because they are only in use for a

fraction of the time.


My Reel Won’t Retract at All!?!

Freight damage

• Series DP reels leave the

factory in a double wall,

corrugated cardboard box. They

are enclosed in a bag and have

high density foam inserts to

protect the reel.

• It is always wise to inspect the

packaging before receipt of a

reel. If the packaging is

damaged, un-box and ensure

that the reel operates smoothly

and there are no dents,

scratches or dings in the sheet

metal before signing for

delivery.

Latch out

• Latching parts are mounted on

the guide arm, therefore; it is

impossible to latch this reel out

at full extension.

• There is a U-bolt on these

models, but only one position. It

is designed to alleviate tension

on the swivel from hose pull.


My Reel Will Not Retract at All!?!

Damaged, disassembled or

missing latch spring

• The latch spring holds the

pawl tight to the ratchet.

• Over the life of a reel, latch

springs may stretch while they

wear and become ineffective.

• Investigate & replace latch

spring.

Constant tension

• Reelcraft offers most all of it’s

latching reels in a constant

tension version as well. This will

be designated in the part

number with a “-CT” suffix.

DP7650 OLP (standard)

DP7650 OLP-CT (constant tension)


My Reel Won’t Latch!?!

Add tension

• Coil springs with time will

loose some of their tension.

Customer supplied hose

• Customer’s hose may not

meet our minimum bend radius

or recommended O.D.

Reel mounted in excess of 15’

overhead

• This type of installation

necessitates that the bumper be

set such that 15’ or more of

hose is hanging off the reel at

all times. In turn, tension is

increased on the drive spring,

causing it to wear prematurely

or in extreme cases fail entirely.

• Always consult engineering in

this type of application.

My Reel is Making an Alarming Noise

Intermittent coil release

• Suction is generated between

coils causing the retraction of

hose to be sporadic, usually

accompanied by an out of the

ordinary noise.

• Usually a warranty issue.

Spring thump

• It is typically evident when the

hose is allowed to retract quickly.

• Caused by excess movement of

spring assembly within the spring

pan.

• It is not detrimental to the reel’s

function.


My Reel Isn’t Building Any Tension!?!

Spring form broken

• The part of the spring that

engages the arbor has fractured

causing the spring to spin freely of

the arbor.

• If experienced in warranty

period, potential return


My Reel is Leaking At The Swivel Union!?!

If the leak has occurred at the threaded portion that

mates to the main shaft, the most likely fix will be

further tightening the swivel or additional pipe tape.

Leaks may also occur at either end of the swivel

body. The cause of this type of leak is a failure in

the O-ring(s).

Leaks at either the threaded portion where the ell

meets the swivel body or where the ell attaches to

the hose can generally be corrected with either

tightening or additional pipe tape.

It is always important to verify that compatible

fittings are used. Our most common is National

Pipe Thread Fitting (NPTF or NPT, for short).


Servicing a Balanced Style Swivel

The stem can be

disassembled from the

swivel body by removing

an external snap ring.

O-rings are wear items

and can possibly leak.

NOTE: Different swivel designs will incorporate a different

number of o-rings and/or backup o-rings.


Servicing a Ball-Bearing Style Swivel

Step 1: Remove

grease fitting.

Step 2: Remove ball bearings through grease port. Note:

there may be grease making this difficult. If needed pre-

soak with de-greaser. The stem will not separate from

the body unless all ball bearings are removed.

Step 3: Replace worn /

damaged O-rings / back-up O-

rings. Service kits are available

for most swivels.

Step 4: Re-assemble swivel stem and body. Replace all bearings and then grease fitting.

Grease fitting and assemble back onto main shaft of the hose reel.
