1. As in all previous posts, when you are not using your pump, you should clean and store the pump in a warm & dry location.
2. Before you reinstall the pump, locate the phillips head screw that can be found in-between the stainless steel and fiber plastic on the Tsurumi Pond Pumps. Place the pump flat down with the phillips screw pointing upwards. Unscrew the screw and check the level of the oil. If the oil is low, you should fill the cavity with a Di-Electric mineral oil. As you are filling the oil, you should spin the impeller slowly with your finger (never perform this while the pump is plugged into an electrical source). Spinning the impeller will allow the oil to fill the oil chamber while releasing any air gaps. Close the screw tightly once finished and make sure there are no leaks.
3. Inspecting the electrical cord is an important step that should not be overlooked. As time passes, the cord can frey and wear causing an electrical malfunction and chance of electrocuting any life you many have in the pond. Clean the cord from top to bottom and carefully inspect for exposed wiring or thin insulation. Should you find any of these conditions, do not reinstall the pump until the power cord has been replaced. You can contact us to purchase a new cord: (888) 647-8677.
4. If you are somewhat familiar with pumps, we recommend disassembling the pump and inspecting the gaskets and O-rings. These vital parts prevent water from entering you motor and causing an electrical failure. Please do not attempt if you are not familiar with pumps.
5. Check the operation of the pump out of water. Plug the pump into an electrical source and run the pump for 30 seconds. This will save you time installing a faulty pump.

Tsurumi generators vs. Honda brand generators

Tsurumi is a premium grade generator: There are three manufacturers of what we consider to be premium contractor grade generators. They are Tsurumi, Honda and Multiquip. This is important as there are several medium and low grade generators also being marketed. These are great for the homeowner but our customers demand high quality, low maintenance at a fair price from a company that stands behind what they make. Of the three premium generators we feel that Tsurumi is not only the best in quality but also the most competitively priced.

Honda Engine:  Tsurumi has the exact same Honda engine quiet package which consists of the oversized muffler, large air filter and vacuum assist on the carburetor choke. Aside from Honda no other manufacturer has this Honda option available to them.

Voltage Regulation:  Tsurumi uses a condenser voltage regulator which is less expensive and more durable than Honda’s AVR (automatic voltage regulator). Honda’s AVR does not hold up well in field use for construction applications. Honda’s AVR board is less durable, more susceptible to burn out due to voltage fluctuation and more expensive to replace than Tsurumi’s condenser regulator. Example: Our condenser set lists for only $29.00. Over a recent two year period we have only sold 7 of these. To replace Honda’s AVR board will cost your customer over $200.00 according to a local Honda Dealer. This doesn’t include money lost having the generator out of service. If you are trying to sell Tsurumi generators to a Honda customer/dealer and they also repair generators see if you can speak with the service tech. Ask the service tech how often he replaces AVR boards on the Honda generators.

Outlets:  Outlets on Tsurumi generators run in parallel while Honda and many of our competitors run their outlets in tandem. What this means is that if one Honda generator outlet burns out at a jobsite all of the outlets are rendered useless while on a Tsurumi generator just the one outlet is compromised.

Warranty:  Tsurumi generators have a two year warranty on all models. According to our local Honda dealer…”Honda rarely honors a warranty. They always find a reason to blame the user” What is your Honda dealers experience?

End user: When the end user requests a Honda generator he most likely is requesting a generator with a Honda engine and not necessarily a Honda brand generator. Tsurumi offers a nice alternative that is more economical and includes all of the premium features that Honda does and more.

1. Tsurumi pond pumps have dual inside mechanical with Silicon Carbide vs. Ceramic bottom faces. Silicon carbide seals are the best choice for abrasive material handling. In the pond pump application this includes algae, mud, sand and pebbles.
2. Tsurumi pond pumps are comprised of stainless steel and composite resin materials, making it lightweight, durable and rust proof.
3. Tsurumi pond pumps have Watertight Cable Entrance with Anti-wicking block.
4. Tsurumi pond pumps have permanently lubricated sealed ball bearings rated B-10 60,000 hours. The only oil in the pump is located in the small mechanical seal chamber.
5. Tsurumi pond pumps have built in motor protection. Giving the consumer and extra form of built in protection.
6. Tsurumi pond pumps have continuous duty air filled copper wound highly efficient motor. Air filled motors pull less Amps and are more efficient then their “oil filled” counter parts.

8. Tsurumi pond pumps have ball type air relief valve to prevent the submersible pump from air locking.
9. Tsurumi pond pumps have solids handling semi-vortex impeller.
10. Tsurumi pond pumps have energy efficient motors, helping you save on the costly electric bills.
11. Tsurumi pond pumps have an industry leading 2 year warrantee from date of purchase.

1. LSC1.4S: Tsurumi 1/2 H.P. 1/115V, submersible pitless sump pump with a 3/4″ discharge. This sump pump with attach to a standard 3/4″ garden hose for easy pump out situations. The LSC will pump approximately 15 Gallons Per Minute. This sump pump will pump down to 3/64″ and has a built in check valve. This sump pump is only available as a manual pump. As with most of the Tsurumi sump pumps, it’s 3/4″ discharge can be redirected to a 45 degree angle to avoid kinking on the discharge hose. This is achieved by opening the two stainless steel nuts on the sump pumps discharge and turning the discharge fitting. The LSC sump pump weighs only 28lbs, and is easily moved from room to room if needed. The LSC sump pump does have to be primed before each use.
2. LSR2.4S: Tsurumi 2/3 H.P. 1/115V, submersible pitless sump pump with a 2″ discharge. This sump pump with attach to a standard 2″ discharge hose (2″ collapsable discharge hose can be found on our website under the “accessories” page) for easy pump out situations. The LSR will pump approximately 50 Gallons Per Minute. This sump pump will pump down to 1/4″. This sump pump is manual pump but, is also available as an automatic version: LSRA2.4S.  As with most of the Tsurumi sump pumps, it’s 2″ discharge can be redirected to a 45 degree angle to avoid kinking on the discharge hose. This is achieved by opening the two stainless steel nuts on the sump pumps discharge and turning the discharge fitting. The LSR sump pump weighs only 28lbs, and is easily moved from room to room if needed.

• Pond pumps should not be sized only on the basis of  GPH or GPM (Gallons Per Hour or Gallons Per Minute) flow conditions. The most important factor that is commonly disregarded is TDH (Total Dynamic Head). The TDH or lift on your system is crucial to sizing up a pond pump. If you chose a pond pump that has the correct flow without taking into account lift, you will overload the pond pump and cause the seals and bearings to fail, in turn causing the motor to fail. An easy way to think of TDH in regards to a pond pump is comparable to putting a 300 H.P. engine into a a go cart. All that would happen is the engine would fail due to improper sizing. Make sure that your pond installer takes into account the TDH or lift on your pond pump system.

• If the pond pump is not in use for the the entire year, it is recommended the pond pump be removed from the water, cleaned, dried and stored in s warm dry location. One of the biggest misconceptions is that the pond pump should be submerged in a bucket of water. Not only is this the incorrect way to store an unused pond pump but it cause damage to the pump once it is turned on again for the first time.
• It is strongly recommended that the oil level of the pond pump be checked prior to operation in each pond pump season. Tsurumi pond pumps have a “phillips” head screw, half way between the stainless steel and pump housing that stores the oil. Place the Tsurumi pond pump on it’s side with the screw facing upwards. Check the oil level and if needed apply Di-Electric oil into the oil chamber while spinning the impeller with your hand. Spinning the pond pump impeller will release any air in the oil chamber and allow the oil to fill the chamber. All Tsurumi pond pumps are air filled motors, there is no oil or any other liquid that should be in the Tsurumi pond pump motor housing. Should you see any liquid in the pond pump motor  housing, it is likely the mechanical seals have failed and need to be replaced before operating the pond pump again.
• Tsurumi pond pump come with a 20′ or 32′ power cable. It is strongly recommended inspecting the power cables prior to operation each pond pump season to make sure there are no breaks in the water proof coating of the cable. Should a pond pump cable be exposed to water, it would cause the pond pump motor to “burn out” and make the pond pump inoperable and unrepairable.
