FAQs
What is the difference between the WS30 and WS50?
The primary differences are horsepower and impeller design. The WS30 is a 1/3 HP pump designed for lighter loads, whereas the WS50 is a 1/2 HP pump. Additionally, the WS30 uses a three-vane impeller, while the WS50 uses a two-vane design.
How much solids can the WS30 handle?
The Monarch WS30 series can pass spherical solids up to 11/16 inches in diameter, making it suitable for effluent and very light sewage applications.
Is the WS30AM automatic?
Yes, models designated with “AM” (such as WS30AM) come equipped with a mercury-free piggyback style float switch for automatic operation.
Does the pump use oil or water cooling?
The motor chamber is oil-filled (approximately 2.1 liters for the WS30) which provides continuous lubrication for the double ball bearings and acts as a coolant.
