Pump Hoses: Getting the Right Setup for Your Honda Pump

Pump Hoses: Getting the Right Setup for Your Honda Pump

Buying a pump is easy, but it can be a lot harder picking the right hoses. Which hose materials should you choose? What about thread compatibility? What’s the difference between a basket strainer and a skimmer strainer? Here’s what you need to know to choose the right combination of parts to fit your needs.

Hoses

The optimum hose length is the minimum you need to get the job done. As length increases so does flow resistance, which can reduce your pump’s performance.

Intake hoses need to have an internal structure to resist vacuum forces. PVC hoses are good for general use, while EPDM is more abrasion resistant, making it a good choice for trash pumps.

Discharge hoses have to withstand outward pressure, but these stresses are much lower than those experienced by the intake hose. Basic lay flat hose has a low-pressure rating, typically below 80 PSI, and is intended for pumping water downhill or across flat surfaces. When pumping water over slight inclines, look for a hose with at least a 150 PSI. As with intake hoses, EPDM lining is the best choice for trash pumps.

Keep in mind that pressure ratings for all hoses are based on an operating temperature of 68ºF. Maximum pressure will decrease in higher temperatures, so it’s better to err on the safe side if you regularly pump warm water.

Connector Types

Pin lug ends use threads like a garden hose. These usually need to be tightened down with a large spanner. Hoses typically come with threads on both ends so multiple hoses can be connected using to get the right length. All Honda pumps have pin lug threads on the intake and discharge openings.

Camlock ends use a quick connect system with two cam arms that fold in to lock the hose in place. This allows the hose to be connected and removed without the use of tools. Camlock adapters can be added to threaded connectors, including the openings on your Honda pump.

Threads and Gaskets

There are two widely used thread standards on water and trash pumps: NST and NPSH. NST is National Standard Thread, another name for NFPA 1963. This thread is common on firefighting equipment. NPSH is National Pipe Straight Hose thread. It’s slightly smaller in diameter than NST, and it has more threads per inch. This thread is commonly used on water and trash pumps across the industry, including Honda’s pumps. Both threads are straight, so they don’t self-seal like tapered plumbing threads. To make the connections water-tight, a separate seal must be added to the face of the connector.

Strainers

A strainer covers the opening of the intake hose to block materials that are too big for the pump to handle. Hole size should be chosen based on the maximum debris size your pump can handle. As for materials, plastic works well for regular pumps, while metal can withstand impacts from large debris drawn in by trash and diaphragm pumps.

Basket strainers work well for general use, while skimmer strainers are best for completely draining bodies of water. These have a low profile to pull in water until it’s almost gone without starving the pump.

What Type of Pump Do I Need?

Flow Rates in the Real World

The flow rates below are in ideal conditions, but there are two factors that can reduce the actual flow rate once put in use:

The head, which is the difference in height between the end of the intake hose, the pump and the end of the outlet hose, will affect pumping performance. If all three points are at about the same height, the pump should work at the rated gallons per minute. If the height difference is high, say, when pumping water out of a well, the pump has to overcome gravity, reducing the flow rate.

When it comes to trash and chemical pumps, the fluid being moved may be heavier than water, which further decreases pumping speeds.

Before you buy a pump, check the detailed specifications to make sure the pump will be able to support the total head you’ll need the pump to handle. If you need to maintain a specific flow rate, download Honda’s free “Pump Select software“. It can do the flow calculations for you and make model recommendations.

The gallon per minute rating may get the most attention, but the main factor when selecting a pump is its intended use:

Portable De-Watering

The WX Series is built for high portability with the WX10 weighing just 13 lbs. These models are great for occasional use for gardening, boat maintenance, and general household usage, moving between 32 and 74 gallons of water per minute.

General De-Watering

The WB series trades the WX’s low weight for more pumping power. Commercial grade components including silicone carbide seals and anti-vibration mounts help with long term reliability. They can move between 164 and 290 gallons per minute.

Nozzles, Sprinklers and Long Distance Applications

The WH series is built for high-pressure applications while still being portable, making them a great choice for irrigation and fire suppression. These models can pump up to 119 GPM under pressures as high as 64 psi.

Chemicals

The WMP20 is designed with materials that resist corrosion and damage from a wide range of industrial and agricultural chemicals as well as salt water. Keep in mind that while it can handle both base and acidic fluids, it can’t pump just anything: Honda keeps an updated list of approved chemicals on their site. This pump has a maximum flow rate of 220 GPM.

Trash, Debris, and Big Jobs

The WT Series is built for moving massive amounts of water that is mixed with solids up to 1 1/16 inches in diameter. A quick clean out port and design features for easy maintenance make these pumps more than up to the task of handling the demands of contractors and rental businesses. These pumps can move between 185 and 433 gallons of water per minute, although high trash content will reduce performance.

Severe Duty and Slow Seepage

The WDP30 uses a positive displacement diaphragm pump that can move water that contains up to 25% solids including mud and trash. This design can also run dry without harming the seals, while a rock channel in the volute case and spring-loaded connecting rod protect the components from impacts. That capability comes at a cost of pumping speed, limiting it to 80 GPM.

Fixed Locations

Honda’s WSP electric pumps are powered by 120 AC current, making them a great choice in areas that have frequent need of pumping and have ready power access. These units have switches to pump automatically once the water reaches a certain level, and they’re also set up so they can be put in continuous use. Electric pumps are great for draining water from tanks and containers including pools and hot tubs as well as removing seepage in basements and powering fountains and garden irrigation systems.

Most models are designed for plain water, but the WSP 50 and 100 models are both trash pumps, able to handle solids up to two inches in diameter. Pumping speed ranges from 40 to 150 gallons per minute.
